* Remaining push constant issues should be phased out, more changes to
come regarding declaring shader resources to make it less error-prone,.
* Sampler creation is restored for create_texture, for now.
* EndRenderPass command type is now supported, to partially reset render
state when needed.
This is a huge change, and basically breaks everything (as per usual!)
First of, this includes stuff like shaders so anything involving those
are broken and then fixed. A new BuildAssets cmake file is added to
aid in running AssetCompiler, and it seems to work fine on the engine
base assets.
The File API will eventually be revamped to handle this new way of
organizing the files and domains will eventually be gotten rid of all
together since I probably will replace it with game directory
priorities. As it stands right now, there isn't a way to easily
replace say - render_options.cfg with your own game-specific version.
Apple builds are probably broken by this commit (since I'm moving
around content and shader directories) to be fixed later.
All specialization constants are removed (they cause trouble in
WebGPU, since they don't support array sizing, and it was a pain
in Metal anyway) - they are now macro defined. WebGPU now runs, although
push constant emulation is not implemented yet.
This is to be in line with requirements from HLSL/DX12 and WebGPU,
both of which do not support this. It's probably better to get
started removing our usage of them now :-)
Now it's even simpler, and it now generates multiple
shader languages at once! The copying mechanism is now
much simpler on non-mac platforms as well. HLSL is also now a supported shader target language.
