3902628e35 Support WebGL 1.0 with caps
There is some logic in here for 2.0 as well, just as a
"as long as I was looking at the specs", but only 1.0
is really supported.

This seems to resolve the bug where some GPUs weren't
advertising correctly that they had vertex array object
support, by checking for both extension names (with and
without "GL_" prefix)

Of note, this saves about 18 Kb (5.5 Kb gzipped) of code size
by compiling out the unneeded GLES checks/functionality.

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.
