Original change's description:
> Add Atlas Text interface for rendering SDF glyphs.
> 
> This new API is built upon SDF text atlas code from the GPU backend. Unlike using the GPU
> backend to draw text, this set of interfaces allows the client to render the SDF glyphs. The
> client issues text draws to potentially multiple targets and then the client flushes. The
> client then gets commands from Skia with data to put into a texture atlas and vertices to
> draw that reference the texture. The client is responsible for creating the texture, uploading
> the SDF data to the texture, and drawing the vertices provided by Skia.
