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.
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.
Now it's much more usable, you are forced to use a hosted
shader compiler on a platform that needs it (for example, iOS)
and now CMake will error when it's missing. Now every
platform is very specific on which languages it needs to
be translated to, and whether a hosted compiler
is needed. No more manually copying over shaders!
* Now shader recompilation happens only when it needs to. Hurray for faster compiles!
* Changes to constructors for ShaderSource to make it more explicit.
* The version of SPIRV-Cross is updated, and now the glslang version pulled correctly matches what SPIRV-Cross needs. This fixes the annoying "cannot parse built-ins" bug.
