GLContextEGL requires extension "EGL_ANGLE_surface_d3d_share_handle", which no longer exists. According to the extension spec, the extension was renamed in version 2 to "EGL_ANGLE_surface_d3d_texture_2d_share_handle", but this change was evidently never factored back into GLContextEGL.

EGL_ANGLE_surface_d3d_share_handle only ever existed in a local patch that we used to have, not in upstream ANGLE.

When I upgraded ANGLE to r653 (bug 657748), I removed this patch as that functionality had been integrated upstream. I didn't notice that the extension name was different.

Can anyone please help me with a test case or with STR / guidelines that I can use to verify this fix?

Thank you

Actually, no, it's not very easy to verify this one. The only user-visible difference is speed: when we had this bug, running WebGL demos with a large window or full-screen was slower than normal.

In order to prevent this kind of regression in the future, we need WebGL performance tests: bug 676138.

qa- as no QA fix verification needed
