#change - RHICopyToResolveTarget now uses a compute shader. Now have the ability to copy from a tiled to a non-tiled texture. (Also slightly faster). #change - RHIUpdateTexture2D now uses a compute shader so it can work with tiled textures. (Also slightly faster). #change - Surfaces created with CPUReadback are forced to be linear so that the CPU can read them directly. #change - HZB occlusion culling now works on PS4.
