Collision circle generation at runtime #9219

mpulkki-mapbox · 2020-01-22T15:12:29Z

Collision circle generation logic is currently performed in two different coordinate spaces, tile and label space, and the final decision of which circles to use is made by stitching these results together. First, a certain number of collision circle candidates are pre-generated for each label in tile space. Secondly, circles that should be used in collision check are determined at runtime. Some of the previous work can be found here #5474.

Limitations and problems with this approach becomes apparent quite fast. There seems to be quite a lot of approximation logic in the code that produce correct looking results but start to break down with certain input. The biggest issues we're facing if we were to remove the 60 degree pitch limit:

The number of generated collision circles per label are 300% of what would normally be the max size. This might not be enough as some labels might extend past the padding.
Projection from label space to tile space is a crude approximation that produces inaccurate results. This might result in too few collision circles being used.
Perspective correction is not taken into account when choosing which collision circles to use.

These problems are difficult to solve without modifying the underlying algorithm. It would be possible to increase the number of generated collision circle candidates and improve the tile projection approximation, but it would just move the problem forward and not fix it. This pull requests implements 100% runtime collision circle generation that has already been brought up #5474. Some of the benefits of this approach are:

Very simple to implement. Most of the required code is already written and can be reused.
You get what you see. Same code is used for rendering and collision checks. No more crude approximations.
No need for persistent storage for pregenerated circles.
Perspective correction is properly applied for glyphs.

The code has been simplified to place collision circles by interpolating between road vertices on the label plane. Interpolation itself is cheap and the label plane information is a by-product that has been already computed during previous steps.

I'm expecting to see reduced number of collision circles especially with distant labels. The old implementation has to use somewhat expensive vertex projection for each collision circle candidate to see if it should be used in the collision check. This does not scale well with distant labels where you might need to go through 20 candidates to only use 4 of them. This is unnecessary as the screen space coverage is already known.

I need to run some benchmarks to see if there's any difference in performance. Debug rendering of collision circle placement is a bit more complex now with only screen space coordinates available, but the performance hit should be small.

(update to the previous post)

Overview

This pull request transforms collision circle generation into a runtime operation. Motivation behind the change is to have a more precise and flexible collision detection for line labels that sets no expectations for camera orientation. The new placement logic shares code with rendering to better reflect what's actually visible on the screen.

This has become a relevant issue now that we're ready to support lod-based tile streaming. The current implementation is not a scalable solution to be used with less constrained camera as some corner cases like inaccuracies in collision detection are already present with the 60 degree pitch limitation. Improving line label placement is a prerequisite for increasing the maximum pitch angle and for any 3d-related features we may end up doing in the future.

What's new?

The core idea behind this change is quite simple and well defined, but lot of supporting code had to be updated as well.

Collision circles are no longer pre-generated during the symbol layout process
Collision circles were previously generated during performSymbolLayout in a worker thread as part of the bucket creation process. A certain number of circles were created for each collision feature in tile coordinates and then serialized together with collision boxes. Shapes used for both collision detection and rendering were later deserialized from this array.

The new role of performSymbolLayout involves evaluating collision circle diameter (previously text height) per feature and setting a flag to notify if collision circle generation should be done at runtime. Pixel based property Text-padding is also applied during runtime.
Collision circle generation at runtime
Collision circle candidates used in collision check were previously determined by finding positions of the first and last glyph on the label plane and then approximating their distances from the tile anchor. These distances were then compared to circle offsets in order to find the most optimal circle coverage for the label. I found this part of the algorithm particularly difficult to follow as it seemed to use very different numbers for transformations compared to the rendering logic.

The new approach uses screen space projection of the label path to find the most optimal number of collision circles. The projected path is already available as the very same information is required to determine which pregenerated collision circles to activate. The usage of this data should add no extra costs as collision checks are performed in screen coordinates which happens to be identical to the non-pitched label space (with a small translation added for viewport padding). An extra transformation step has to be done though for labels in pitched label plane in order to find their screen coordinates.

An example comparison. Left: master, right: new

Added flexibility (first two images: less circles, 3rd image: extra padding)
Ownership of the debug data
With a fixed number of collision circles per bucket it was easy to create static sized vertex and index buffers for the data. Static vertex properties were stored in their own vertex buffer while more dynamic properties like "isUsed" and "hasCollision" were uploaded to gpu in their own vb after the placement process was finished.

These buffers have now been removed and dynamic properties of debug circles (center_x, center_y, radius, flags) are stored in the Placement-class until the placement operation has been finished. Debug circles are pushed together with projection matrices to their corresponding buckets in commit().
Debug rendering
Debug rendering is a bit more difficult task now that circles are stored directly in screen space coordinates. It wouldn't be a problem if positions were updated every frame before rendering, but the symbol placement is a continuous process that can span over multiple frames invalidating previously computed positions if camera moves. Screen space coordinates are always bound to a specific camera position and orientation. The solution is to re-project circles from the placement screen space to the new one used in rendering.

To render an arbitrary number of circles I ended up implementing a simple webgl 1.0 compatible shader instancing that requires no extra extensions. Circles are sent to the gpu in batches of 64 instances encoded in a single vec4 uniform array and vertex data is just a collection of incremental index values. Memory footprint of this approach is small as only 16 bytes per circle is needed to be uploaded to the gpu.
```
// javascript
const vertex_data = [0, 0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5,...];  // 2 values per vertex
```
```
// glsl
uniform vec4 u_quads[64];
attribute vec2 a_idx;
...
int quad_idx = floor(a_idx.x / 4);
int vertex_idx = a_idx.x % 4;
```
Alternative instancing/rendering implementations:
- WebGL instancing
  - Not a WebGL 1.0 baseline feature
- Single vertex buffer, circular update
  - Idea would be to append vertex data to the end of the buffer and start from the beginning when the buffer is full. Downside of this approach is that bufferSubData is not guaranteed to be an async operation. Some kind of "no_overwrite" flag and explicit buffer orphaning would be required as well.
- Encoding instance data into a texture
  - Vertex texture fetch support is not required in WebGL 1.0

Perspective correction of line labels is fixed
Perspective correction formula is (according to Text Rendering)

const perspectiveRatio = 0.5 + 0.5 * (camera_to_center / camera_to_anchor);
const pitchScaledFontSize = pitchWithMap
  ? fontSize / perspectiveRatio
  : fontSize * perspectiveRatio;

updateLineLabels in projection.js was using inverse of the perspective correction algorithm which produced squeezed labels near bottom and top of the screen:

const perspectiveRatio = 0.5 + 0.5 * (camera_to_anchor / camera_to_center);
const pitchScaledFontSize = pitchWithMap
  ? fontSize * perspectiveRatio
  : fontSize / perspectiveRatio;

This fix effectively resolves the issue reported in ticket Distant line-placed labels are illegible when top padding is large mapbox-gl-native#15167.

What's new for users?

This PR might slightly change the set of visible labels on screen at given time as more precise collision circle placement allows more tightly packed labels. An example from the render tests:

Benchmarks

I could not find any noticeable and reproducible difference in performance between this change and the master. I ran JS benchmarks and did some manual testing as well. I tracked the number of collision circles and boxes added to the collision grid and the number of collision checks done per placement operation. Tests were done using a fast i9 laptop and a slower Amazon Fire HD tablet.

Notes and open questions

Most of the pages debug/*.html were tested.
Text-anchor property is ignored in collision circle placement Text-anchor is not properly supported in collision circle placement #9313 . This PR uses more conservative approach by placing collision circles to cover both "flipped" and "non-flipped" cases.
Text-padding for line labels is now being applied at runtime during collision checks. Previously the padding was applied to circles in the preprocessing step.
Render and query test baselines should be updated. All of the failures are caused by a slightly different layout due to more precise placement. This is of course something that should be confirmed.
Most of the code comments should be updated to reflect the new logic.
draw_collision_debug.js recreates vertex and index buffers for each frame which is not optimal.
There's plenty of room for optimizing the interpolation logic.

good to describe difference in text-anchor behavior, previous vs new (more conservative approach by placing collision circles to cover both "flipped" and "non-flipped" cases).

mpulkki-mapbox · 2020-03-03T09:31:38Z

Thanks for the comments, @astojilj! There are few intended changes that I should open up more.

good to describe difference in text-anchor behavior, previous vs new (more conservative approach by placing collision circles to cover both "flipped" and "non-flipped" cases).

The first one is different handling of flipped vs. non-flipped line labels in circle generation. I noticed some weird behavior in circle placement when text-anchor was used with line labels. Some of the labels were properly covered by collision shapes but about half of them were totally off. After further inspection this was caused by different handling of "flipped" and "non-flipped" labels in rendering and collision detection logic. Collision circle placement is treating all labels as "non-flipped", ie. it doesn't care if labels would appear upside down on the screen. This behavior combined with non-centered text anchor might result in huge misalignment between labels and collision shapes. I reported this issue first here #9313.

I ended up implementing "conservative offsets" for glyph placement where both possibilities are taken into account. Enough circles will be generated to cover both placement cases (as seen in the following image) which should fix problems with horizontal anchor for the cost of a larger area reserved for labels. It might not be the most optimal approach and it's not required for this PR. Perhaps I should cut it out and implement in another PR?

Another intended change is the usage of "Text-padding". Instead of including pixel padding in precomputed collision shapes it's now being added at runtime directly in screen coordinates. It should still conform to the specification "Size of the additional area around the text bounding box used for detecting symbol collisions."

mpulkki-mapbox · 2020-03-03T12:10:15Z

One additional benefit of this change is the reduced memory usage due to circles not being stored anymore. I positioned a map using streets-v10 to few different locations and printed out the number of collision boxes and circles added to the collisionBoxArray during performSymbolLayout operation.

console.log(bucket.layers[0].id + ": " + (bucket.collisionBoxArray.length - preArrayLen));

The number of collision shapes created for all features is down to 5% in this specific overscaled tile. In raw memory usage this is (34757 - 1182) * 24 = 805800 bytes = 806 KB less bytes used. It should also be noted that the previous implementation duplicates collision shapes into a separate array in foreground so the memory reduction could be double of this number. Vertex buffers used to store debug circles are also all gone.

I ended up reverting this fix for now.

mpulkki-mapbox · 2020-03-06T10:42:21Z

All failures in both render tests and query tests are caused by changes in the symbol layout. There are either more visible labels than before or some of the previously invisible labels are now hiding lower priority labels underneath them. Three changes introduced in this PR are causing the failures:

Perspective correction is now properly applied to labels near bottom and top of the screen removing the "squeezed" effect
More precise collider placement allows more labels to be visible
Collision circle debug rendering has changed

I double checked the two failing regression tests and updating them should not have a conflict with original issues (#3534 and #5911).

(I also found out that the perspective correction issue has been addressed before in #5913, but projection.js was not updated at that point.)

@mourner would Array.push be faster than concat?

Yeah — if this is on a hot path, I would rewrite this with a simple for loop to avoid the 3 array allocations.

Thanks for all the changes! This looks ready once tests are updated. The updates for the query tests should probably change the query point, not the output.

@mpulkki-mapbox I haven't looked at the code in detail, just a wild guess: while the PR intends to considerably simplify collision logic, it at the same time adds a few kilobytes to the bundle; could this indicate that maybe there's some potentially unused code that was left in place?

@mourner thanks for bringing this up! I did a small refactoring pass and got rid of few extra bytes. I also double checked that this change should not leave any (significant part of the) code unused. One culprit for the increased size is the debug rendering logic that was previously shared by both box and circle rendering.

@ansis: thanks for the review! I've updated all of the failing query tests.

This disables that after a certain point. fix mapbox#9009 * update rendering after addImage and removeImage (mapbox#9016) fix mapbox#9004 A tile needs to be reparsed in order for it to use the new image. Reloading all tiles whenever an image is added would be expensive. For example: - load a map - add an image and use it in a geojson overlay You don't want adding that image to make the basemap tiles be reloaded. To get around that we track all the image ids used by each tile and only reload tiles that depend on images that changed. * re-add queuing for getResource calls (mapbox#9031) fix mapbox#8998 * Add changelog instructions to PULL_REQUEST_TEMPLATE.md (mapbox#9023) * Add changelog instructions to PULL_REQUEST_TEMPLATE.md * Simplify new changelog related template wording * Place optional changelog entry tags on own line * allow rendering full world smaller than 512px (mapbox#9028) * Clarify toBounds docstring (mapbox#9032) Clarify that toBounds returns LngLatBounds completely containing given radius * implement stretchable icons for icon-text-fit (mapbox#8997) * bump version to 1.7.0-dev (mapbox#9038) * fix collisions for stretchable images with a `content` area (mapbox#9041) * Use stencil test instead of tile mask approach Remove tile masks for raster. Rendering happens in Z-descending order. All the tiles with the same Z use the same stencil value. Parent uses lower stencil value so that the area covered by children gets masked. Stencil ref values continue range used in _tileClippingMaskIDs. * raster-masking test combined with vector. Refactor raster overlap. Return map z -> StencilMode instead of using callbacks. overlapping-vector uses vector layer between two raster to guard against side effects when refactoring stencil usage. * Reset internal attribution control cache when removing from map (mapbox#9052) Fixes mapbox#9051. When creating an attribution control, we're caching the HTML string in the AttributionControl object. That cache wasn't reset when the control was removed from the map. Upon re-adding, we incorrectly assumed that the HTML was already up-to-date because our internal cache said so. This patch fixes it by clearing the internal cache so that attribution shows up properly when re-adding the control. h/t @cs09g * An option to use a feature property as ID for feature state (mapbox#8987) * add ability to id by property for feature state * flow fixes * rework promoteId according to PR discussions * properly expose promoted ids in query methods * fix lint * use state ids that can be cast as Float64 as is; update tests * promoteId: geojson support, better flow typing, v8 docs * fix spec test * make sure id is provided in getFeatureState * minor fixes after review * hash ids > MAX_SAFE_INTEGER * overhaul promoteId validation, add render test * Optimize findLoadedParent Performance optimization when rendering view with a lot of satellite tiles.

This will prevent me from forgetting to remove `-beta` from the changelog when doing a final release. * Fix versions benchmark by querying github API instead of local package.json (mapbox#9084) * Fix map size in benchmarks (mapbox#9049) display: none on Chrome (Chrome 78.0.3904.108 (Official Build) (64-bit) on macos), results with container clientWidth and clientHeight equal to 0. This led to and container dimension [400 x 300](https://github.com/mapbox/mapbox-gl-js/blob/3c36a67716d7c8ad8d69b15f7e5fd19b72e7a7ff/src/ui/map.js#L1922) instead of using specified size in e.g. bench/benchmark/layers.js (1024x768) * Remove `stringContainsRTLText` dependency from within style-spec. (mapbox#9088) * Progressive enhancement for decoding DEM data on workers with ImageBitmap and OffscreenCanvas (mapbox#8845) * Fix validation error messages in the browser (mapbox#9073) We converted the ParsingError and ValidationError classes to inherit from the built-in Error class in mapbox#9025. This works fine in ES6, so our unit tests were happy. However, transpiling it down to ES5 leads to an absence of the message property, essentially removing the text of parsing and validation errors. * Update PULL_REQUEST_TEMPLATE.md (mapbox#9106) the @mapbox/map-design-team tag was incorrect * Remove reference to 'deprecated in expression' (mapbox#9102) * Fix ImageBitmap instances not being passed to appropriate gl.texImage2D call (mapbox#9103) * Un-hardcode test fixtures root path, and add operation handler for 'idle' event (mapbox#9105) * Fix typo in style spec (mapbox#9110) * inline test suite dependencies (mapbox#9096) * Edit convert functions to output linear interpolation (mapbox#9107) * Edit convert functions to output linear interpolation * Edit unit tests to reflect linear interpolation * Refactor code to make it succint * minor whitespace updates * Deferred loading of RTL text plugin detects labels rendered from GeoJSON sources (mapbox#9091) * Add sdk-support section for `is-supported-script` (mapbox#9099) * Add sdk-support section for `is-supported-script` and unit tests to ensure that expressions, paint and layout properties always have an SDK support section. * Fix *-sort-key sdk support table * Remove empty 'data-driven styling' sections and ad dunit tests * Switch back to using host url instead of a blob-url to load rtl-text-plugin on the worker (mapbox#9122) * Change the type of tile id key to string (mapbox#8979) * Change tile id key type from number to string * Add derefLayers to the bundle (mapbox#9121) * Update quads.js (mapbox#9128) whatever it's intended, it's typo. * CP v1.6.1 CHANGELOG (mapbox#9127) * Add instrumentation for performance metrics tracking (mapbox#9035) * Allow programmatic construction of style even when one is not passed in initially ( h/t @stepankuzmin ) (mapbox#8924) * Fix bug in DragRotateHandler._onMouseUp() (mapbox#9137) * Support `ImageBitmap` in Map#addImage and Map#updateImage (mapbox#9139) * Prevent changing bearing via URL hash when rotation is disabled (mapbox#9156) * Immediately update map when more than one geolocation watch event is triggered (mapbox#9092) * fix extrusion querying for: (mapbox#9138) - polygons with coincident points - polygons with less than four points fix mapbox#8999 * Add text-size/zero render test (mapbox#9133) * Add text-size/zero render test Tests that zero `text-size` values are properly handled. * add ignore Co-authored-by: Ansis Brammanis <[email protected]> * update symbol-avoid-edges doc copy to acknowledge the existence of global collision detection (mapbox#9157) * Fix Click on Compass on some mobile (add clickTolerance to DragRotateHandler) (mapbox#9015) * Add layerId parameter to once event handler (mapbox#8875) * Add option to close popup on map move (mapbox#9163) * make placement respect symbol-sort-key (mapbox#9054) * Fix hash (mapbox#9170) * Guard against no bearing in hash on initial page load * Remove log * Add text-color and image to format expression's sdk-support section * Add instructions for changelog authoring to the PR template (mapbox#9165) * Add instructions for changelog authoring to the PR template * Update PULL_REQUEST_TEMPLATE.md * Update PULL_REQUEST_TEMPLATE.md * Update Code of Conduct (v2.0, https links) (mapbox#9176) * update Code of Conduct (v2.0, https links) * Add reporting guidelines & contact email to CoC * Remove outdated link to open source page from CoC * Add spacing for readibility Co-authored-by: Anjana Sofia Vakil <[email protected]> * Update package version to 1.8.0-dev (mapbox#9190) * Prefer line-pattern over line-dasharray in accordance with documentation (mapbox#9189) * Remove Object.values usage that was causing IE11 to fail (mapbox#9193) * LOD support for tile coverage (mapbox#8975) * LOD support for tile coverage * fix promoteId spec definitions (mapbox#9212) * upgrade earcut to v2.2.2 (mapbox#9214) * Fix promoteId for line layers (mapbox#9210) * fix promoteId for line layers * fix promoteId spec definitions (mapbox#9212) * Add render tests for feature state feature-state/promote-id-line will fail until mapbox#9210 is merged Co-authored-by: Karim Naaji <[email protected]> * Fix line distances breaking gradient across tile boundaries (mapbox#9220) * Fix line line distances breaking gradients Ensure scaled line distance is computed at least once when calculating the entire line distance, otherwise we hit a corner case where the distance isn't updated.

When the line pattern fits on a line smaller than its own resolution, we downscale while keeping the aspect ratio at integer zoom level 2. When the line pattern fits on a line larger than its own resolution, we upscale while keeping the aspect ratio at integer zoom level 3. When the line pattern has different resolution (1x, 2x, 3x...), the pattern screenspace resolution should remain stable (e.g. the physical resolution shouldn't impact the size at which the pattern is rendered but instead increase the quality of the visual while keeping its logical resolution) The current behavior does not account for 1. and 3. Shader differences: Try to move for more 'mad' instruction instead of 'div': per-instruction shader count differences: before 6 mad, 12 div, 12 add, 9 mul after 13 mad, 8 div, 6 add, 9 mul This increases the number of mad instructions (multiply-add) for fewer cycles and decreases the number of divisions and additions Issue #15472 * Update test images to account for new behavior * Fix marching-ants issue * Adjust patterns added with `addImage` by the asset pixel ratio (mapbox#9372) * Adjust *-pattern images based on their asset pixel ratio Instead of using the device pixel ratio, use the image asset pixel ratio Fix for issue mapbox#8020 * EOF * Add render tests * Rebase from master Update baseline for line-pattern to take into account mapbox#9266 * Introduce `within` expression (mapbox#9352) * Update version number for GL JS and style spec on master (mapbox#9408) * Fix for IE11 not supporting startsWith (mapbox#9409) * Fix webgl error for IE11 with uploading painter::emptyTexture (mapbox#9410) * Remove Hershey Simplex font attribution from the license (mapbox#9423) * update changelog for v1.8.1 * Upgrade minimist to ^1.2.5 (mapbox#9425) * update pr template team tags (mapbox#9426) * Avoid throwing errors when popup container is undefined (mapbox#9433) * Use TileCoordinates instead of LngLats for `within` calculation (mapbox#9428) * Using TileCoordinates instead of LngLat for within calculation * Update tests * Adapt test data * Add render tests * v1.9.0 (mapbox#9444) (mapbox#9453) * Don't reload the entire font range when a glyph is missing in a font (mapbox#9375) * Ignore missing glyph when font range is already loaded * Add test * lint * Fix tests * Remove line * Remove line * Lint * Add ranges flow definition * Use helpers function * populate paint arrays once per line feature (mapbox#9452) instead of once per linestring in a multiline * fix fill extrusion querying for colinear points (mapbox#9454) When checking for intersections with a fill-extrusion it has to calculate the distance to the plane the polygon exist on. If the first points of the geometry were colinear this calculation would fail. It now: - finds two distinct starting points a, b - loops over all the remaining vertices looking for a value that is not colinear with a, b Usually this will be the first vertex it encounters. * Fix `within` expression issue with geometry crossing the 180th Meridian (mapbox#9440) * Fix geometry accross meridian * Update tests * Add pre-condintion * Avoid overflow * Add more tests * Adapt test * Remove unnecessary condition * Address review findings * Upgrade direct dependencies & do yarn upgrade (mapbox#9466) * upgrade direct dependencies & do yarn upgrade * fix lint warning * 😬 * upgrade more stuff Co-authored-by: Arindam Bose <[email protected]> * add an extra check for paint member of style layer (mapbox#9437) * add an extra check for paint member of style layer * review comments Co-Authored-By: Vladimir Agafonkin <[email protected]> Co-authored-by: Vladimir Agafonkin <[email protected]> * remove leftover page shell (unused since the docs split) (mapbox#9470) * more resilient paint check in setFeatureState (mapbox#9472) * Collision circle generation at runtime (mapbox#9219) * Ensure padding is not propagated from fitBounds to transform padding (mapbox#9481) (cherry picked from commit 7431c95) * Fix pattern attributes vertex layout (mapbox#9482) * Fix vertex layout attribute offset when used with DDS The vertex layout offset for patternAttributes is overriden to be 0, this is incorrect as each component of this layout require a specific offset to be set to appropriately bind the buffers when calling vertexAttribPointer * Fix flow * Cleanup unused param * Add render tests for data driven styling coverage * EOL * optimize tail calls in feature state sorting (mapbox#9463) * Update per mdn webgl recommendations (mapbox#9474) * Update per mdn webgl recommendations - Delete shader handles after succesfull compilation - Query render to half float texture instead of calling checkFramebufferStatus, potentially involving flush + round-trip on first frame * Add heatmap layer to release testing * fix documented type of the locale option to Map (mapbox#9486) * Ensure each tile symbol tile uses its own unique Program based on its state (mapbox#9493) (cherry picked from commit 9f1aba5) * Add `slice` and `index-of` expressions (mapbox#9450) * Allow client to retry RTLTextPlugin load after NetworkError (mapbox#9489) * Fix several listener leaks in popups (mapbox#9498) * Add methods to mapboxgl namespace to allow preloading of workers.

This ensures a clean directory before building the build content and before the manual diffing with previously published tarball. * Address comments * Add scale to Marker options (mapbox#9414) * Change return type to boolean for StyleImageInterface type alias (mapbox#9604) * Fix using `within` expression with complex `filter` (mapbox#9611) * Fix within usage with othere expressions in the same filter * Add render tests * Fix filter operator checking for nested condition * Trigger memory metrics build on CircleCI (mapbox#9622) * Documentation improvements sprint (mapbox#9607) Various documentation enhancements from the docs sprints: * [docsprint] Clarify meaning of Map#isSourceLoaded (mapbox#9589) * [docsprint] Add geolocate trigger example (mapbox#9552) * [docsprint] Add inline snippet to marker#addTo (mapbox#9592) * [docsprint] Add inline snippet and related examples to popup.setHTML (mapbox#9538) * add inline snippet and related examples to popup.setHTML * update see URLs to docs subdomain * Add inline and related example for panTo (mapbox#9547) * Add inline snippet to LngLatBounds.contains (mapbox#9548) * [docsprint] Add inline snippet and examples to map.jumpTo (mapbox#9549) * add inline snippet and examples to map.jumpTo * minor reorder to match options and text * added inline and tutorial examples for map.getCenter (mapbox#9551) * add example for Marker class setLngLat (mapbox#9553) * added examples to get- and setLayoutProperty (mapbox#9554) * add inline snippet and examples to map.triggerRepaint (mapbox#9555) * CameraOptions - update pitch and bearing definitions, add inline code example, add example links (mapbox#9556) * add inline code snippet to map.showTileBoundaries (mapbox#9557) * Mark Debug namespace as private to hide it from the docs (mapbox#9558) * [docsprint] Add detail to docs on setFeatureState, removeFeatureState, getFeatureState (mapbox#9559) * add detail to docs on setFeatureState, removeFeatureState, getFeatureState * remove trailing spaces * [docsprint] map.on: remove extra on section, link to event types, add code snippet, add related (mapbox#9560) * add examples to open and close popup events (mapbox#9565) * [docsprint] Clarify how map.moveLayer works (mapbox#9566) * clarify how map.moveLayer works * fix id capitalization * [doscprint] add links to EPSG and minor example changes for LngLat (mapbox#9570) * add links to EPSG and minor example changes for LngLat * document the layer object's properties in addLayer (mapbox#9571) * [docsprint] Add inline snippet and examples to popup.addTo (mapbox#9572) * added inline example to popup-addto * added relevant examples to popup.addto * Add inline example for trackPointer (mapbox#9575) * Add inline example for Popup#getElement (mapbox#9576) * [docsprint] Add inline examples for Point & PointLike types (mapbox#9577) * Add inline examples for Point & PointLike types * Correct syntax * [docsprint] Cleanup doc for MapBoxZoomEvent (mapbox#9564) * Describe map style object returned by Map#getStyle (mapbox#9579) * [docsprint] Add inline example for getClusterLeaves (mapbox#9580) * [docsprint] PaddingOptions - update definition, example, and related (mapbox#9581) * PaddingOptions - update definition, example, and related * Fixes formatting issues * [docsprint] Add inline snippet to marker#setPopup, marker#getPopup, and marker#togglePopup (mapbox#9582) * update setPopup * update togglePopup * update formatting * update setFilter jsdoc (mapbox#9586) * add more details to getSource (mapbox#9587) * add clearStorage example (mapbox#9588) * [docsprint] Add documentation for RequestParameters (mapbox#9573) * [docsprint] Add inline example for setZoomRate and setWheelZoomRate of scrollZoomHandler (mapbox#9593) * Add inline example for setZoomRate of scrollZoomHandler * add setWheelZoomRate inline example * Add inline examples for map zoom-related methods (mapbox#9594) * [docsprint] Add example to MapMouseEvent (mapbox#9595) * add example to MapMouseEvent * Add examples for GeolocateControl events (mapbox#9596) * [docsprint] Add example to MapDataEvent (mapbox#9597) * add example to MapDataEvent * add example for getLngLat (mapbox#9591) * suggested edits for clarifying mouse events * Small grammar fix: "optional the `layerId`" -> "the optional `layerId" * Update pitch param definition;
