> I think this would be important addition to the GraphicsContext3D implementation in order to get reasonable performance when raw texture mapping cannot be used. Shouldn't be hard to get this integrated. With current implementation code just needs to be moved to GraphicsContext3DImpl::paint().

Simon was of the opinion that we should not support software fallback at all since it is not possible to get descent performance with them.

I tend to agree, that is why I have not updated the patch.

I close this as won't fix. Please comment if you have use case where software fallback are desirable.
