            Bug ID: 220843
           Summary: WebGL power preference and discrete/internal gpu
                    selection implemented incorrectly with ANGLE
           Product: WebKit
           Version: Other
          Hardware: Mac (Intel)
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL

GraphicsContextGLOpenGLCocoa is changing the GPU behind ANGLE's back. This invalidates ANGLE assumptions.
The context gpu is changed based on which window the context is being used on. This cannot work with ANGLE, as all the contexts share one underlying implementation.
