Texture usage flags can now be provided during texture creation specifying the ways in which a texture can be used. This allows the GPU backends to perform contextual optimizations which were not previously possible. This includes enablement of hardware lossless compression which can result in a 15%+ performance uplift for bandwidth-limited scenes on hardware such as Apple-Silicon using Metal. GPU_TEXTURE_USAGE_GENERAL can be used by default if usage is not known ahead of time. Patch will also be relevant for the Vulkan backend.
