[cairo] [PATCH v2 0/3] Enable GLES v3 support

[Bryce Harrington]

Here's a new update of a patchset for adding 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.

This patchset was originally developed by Henry Song.  I posted a rebase
of it last December, and since then I've gone through Henry's full cairo
fork and extracted various refactors and fixes.  I've also incorporated
Uli's review feedback, and split out a couple pieces that could be
landed separately if desired.  A detailed listing of changes since the
RFC is included in the third patch.

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
