Patch by Arvid Nilsson <anilsson@rim.com> on 2012-05-31
Reviewed by George Staikos.

Properly set up resource sharing between WebKit thread EGL contexts and
the compositing thread EGL context, so the texture ID produced by WebGL
and 2D canvas makes sense to the compositing context.

There's no public API to supply an EGLContext yet, so we're lucky that
the embedder never makes its context un-current. Just grab the current
context on the compositing thread and use that as the compositing
context.
