1314338 - Disable OES_EGL_image extension on ATI drivers

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Mason Chang [Inactive] [:mchang]]

ATI drivers don't seem to actually have a function pointer to 'EGLImageTargetRenderbufferStorageOES'. After talking with jgilbert, we shouldn't be using this anywhere anyway, so disable this feature on ATI drivers. This also seems to correlate with this - https://bugzilla.mozilla.org/show_bug.cgi?id=1298333#c6

I'm on an AMD Radeon M395X and the user in bug 1298333 is on a Radeon HD 6310.

Specifically the renderbufferStorage entrypoint, since IIRC we could find the texture one? If not, this text is fine.
