notes on the future queries API

[ianstormtaylor]

Just like for #2873 and #2759, just putting this here as notes for the future. Iterating on a set of queries that will live on editor.* for common use cases.

Schema

isAtomic(object)
isBoundary(node)
isBlock(node)
isInline(node)
isVoid(node)

Creators

createPoint(properties)
createRange(properties)

Points

// Checking point relative to a path.
isAtStart(point, path, { includeZeroWidth: false })
isAtEnd(point, path, { includeZeroWidth: false })
isAtEdge(point, path, { includeZeroWidth: false })

// For moving the point.
getNextPoint(point, { unit: 'offset', includeZeroWidth: false, includeVoid: true })
getPreviousPoint(point, { unit: 'offset', includeZeroWidth: false, includeVoid: true })

// Insertion calculations...
getInsertPoint(point)
getInsertMarks(point)

Paths

getStartOfPath(path)
getEndOfPath(path)
getRangeOfPath(path)

Range

getActiveMarks(range)
getFragment(range)
