Implement GPU-to-GPU texture copy for WebGL 2 and more internal formats |
||||||||||||||||||||||||
Issue descriptionIn WebGL conformance tests tex(Sub)Image2D(3D), GPU-to-GPU texture copy is not fully supported in the case when the input is an HTMLCanvasElement or an ImageBitmap. The un-supported format can be referred in this function: WebGLRenderingContextBase::canUseTexImageByGPU We should implement GPU-GPU texture copy for WebGL 2.0 and more internal formats.

Seems that this issue is duplicated with this one: https://bugs.chromium.org/p/chromium/issues/detail?id=612542.
