Better example for custom Icons for AppBar

[brean]

Overview

Some icons for the AppBar instead of the generic ObjectCollectionScatter, to look a bit more like the version from the Holograms app

Changes

• Fixes: Change AppBar Icon #2310 .

why svg instead of png?

[StephenHodgson]

Oh I see you included both.

[brean]

Yeah, I added the original files, makes it easier for others to either modify existing icons or add new icons based on these.

[StephenHodgson]

I think we'll def use TextMeshPro to make the default icon pack for vNEXT.

@cre8ivepark should review the look of these new icons

Thanks! @brean We were not able to include icon glyph font files and images of the glyphs since we cannot publish them in the open-source projects. (font license/design patent issue).
We provide HoloLens MDL font from Dev Center with proper EULA file. Developers can manually import into Unity and generate the texture from this font file.
https://docs.microsoft.com/en-us/windows/uwp/design/downloads/

I agree that we need better documentation for this & tools. (something that can automatically generate icon texture from the font file - we had this feature in MixedRealityDesignLabs. Needs porting work)

I'll clone your repo and check out your icon design today. Thank you!

@cre8ivepark if we were to generate the icons with a tool like TextMeshPro without including the source font itself in the project, would that satisfy the licensing constraints?

The end result would just be a texture.

I checked out the design. Since your design is very close to the original design, I think it would be better to just use the original design from HoloLens MDL font glyphs. I'll apply the updated texture to your repository this weekend. Thanks!

@brean , I applied changes to your repository. Thank you!

• Updated textures to the original design.
• Changed the location of the textures to existing HoloToolkit/UX/Textures/Icons. Textures under HoloToolkit-Examples folder will break the app bar when the user doesn't have HoloToolkit-Examples folder.
• Removed SVG files. People can use existing icon texture (512x512) png file and HoloLens MDL font as a template.
• Updated icon font material to use emission color. (icon was shaded depending on the direction, by the lighting condition)
