1574232 - Enable WebGL for android emulators.

Status: NEW

(Core :: Graphics: CanvasWebGL, enhancement, P3)

Description

[Randall Barker [:rbarker]]

WebGL currently fails in GeckoView when run on android x86 emulators. It would help facilitate development and testing to be able to use WebGL on an emulator.

If I try to do any WebGL stuff on the emulator, I immediately get a deadlock in SharedSurface_SurfaceTexture::Commit(). It seems that either the emulator has a bug there or we're not correctly waiting on that buffer to become available.

Not sure if this is directly related, but this issue reminds me of the code kats added for webrender:
