703487 - Implement ARB_robustness in WGL

Status: RESOLVED FIXED

(Core :: Graphics: CanvasWebGL, defect)

Description

[Doug Sherk (:drs) (inactive)]

Another low-hanging fruit of ARB_robustness. GLX is already done, which provides 90% of the framework for this. WGL has its own ARB_robustness extension which we need to load and handle correctly. There should be no work here outside thebes.

Attachment: Patch v1.0, WGL implementation of ARB_robustness.

This is being activated completely fine and all the infrastructure to support it seems to work correctly (i.e. the stuff that was written for GLX ARB_robustness), but creating a robust context on WGL seems to do nothing on my machine; i.e. if I DoS the GPU it crashes the same as if it wasn't enabled. Perhaps my machine just doesn't properly support it, or the drivers state that they do but actually don't.

Not sure what's up with the failed Android build. This should have no impact on Android so I'm not too worried about it. Almost every other try build today is getting that same red/burn.
