	4a835cf2	2024-11-01T13:31:00		WebGPU: send uniforms to GPU for use in shader Basic uniforms should now be accessible in the shader during a draw call, rather than just via glGetUniform*(). This is unoptimized and creates a new GPU-side copy of all the uniforms, every time any uniform changes. This sets up the bind group layout for a pipeline and sets the bind groups in the renderer pass. Right now these bind groups only contain the default uniform blocks, but in the future will need to contain textures, samplers, and non-default uniform blocks (UBOs).

	a6ee4641	2024-09-25T11:41:47		WGSL: Output default uniform block and accesses to it Default uniforms are put into a WGSL struct, and all accesses of those uniforms now output struct accesses. Similarly to I/O vars and builtins, these are outputted in a pre-pass, but in the future it might make sense to do what Vulkan does and do an AST transformation to put the default uniforms into a UBO which should be outputted similarly. This does not handle bool, matCx2, or array of element size < 16.
