[cairo] [PATCH 0/3] [RFC] Enable GLES v3 support

[Bryce Harrington]

This is a rebase to trunk of a patchset from Henry Song to add Open GL
ES 3.0 support to Cairo.  Currently Cairo supports only OpenGL ES 2.0,
which was published in 2007, so this moves us 5 years closer to modern
day.

I've done some light testing to make sure it works.  While the GL
backend is still quite experimental and not enabled by default, there
are a few test failures that I want to investigate further before
landing.  However, right now I'm more interested in getting feedback on
the implementation approach.  I know this is a huge patchset, but any
code review assistance would be greatly appreciated.

Bryce Harrington (3):
  gl: Convert images to rgba or a8 formats when uploading with GLESv2
  gl: Make _cairo_gl_ensure_framebuffer a private shared routine
  gl: add support for OpenGL ES 3.0
