Plumb through EGL_NV_post_sub_buffer and GLX_MESA_copy_sub_buffer.
These two extensions allow a partial swap: just pushing part of the backbuffer to the front buffer. This will allow the WK compositor to push a partial update to the screen instead of a full frame update (https://bugs.webkit.org/show_bug.cgi?id=70533).
We should be able to do something similar for TOUCHUI ImageTransportSurfaces (hence the hooks into GLSurface and the glPostSubBufferCHROMIUM command).
