[webkit-dev] Proposal: Remove TextureMapperImageBuffer

A slight update on this issue. It's already been attempted here:
The issue is that WebKitEFL is using the TextureMapperImageBuffer to
run tests on their bots, because the EFL bots don't support OpenGL
tests. My suggestion is that we disable accelerated compositing
completely for WebKitEFL (if possible) and skip those tests. Once the
bots have the ability to run tests that use OpenGL, we can re-enable
that code path for WebKitEFL.
