Previously we would modify the GL state as soon as we saw
SetIndex/VertexBuffers. This GL state is owned by the VAOs in the
InputState and was disappearing on a Pipeline change. Fix this by
applying the index / vertex buffers lazily.
This was because the clip space of OpenGL has an inverted Y compared to
other APIs. This commit:
- Updates SPIRV-Cross to the latest version
- Uses the new vertex.flip_vert_y option in ShaderModuleGL
- Enables tests that are now passing in GL.
Explicitly configure swap chain usage in bindings and examples

* clang/gcc: enable -pedantic warnings
* suppress a GCC-specific warning in stb_image
* And some clang-specific warnings
* -Wconversion (clang) -Wold-style-cast (clang+gcc)
and fix a few warnings that show up with these (and a few more with
-Wconversion on gcc, even though that's not enabled by default)
* bunch more warnings
* fixes
* remove merge error
Adds the swap chain interfaces to the API without changing the behavior
of anything else. This includes the C APIs for applications to provide
swap chain implementations. Also adds stub implementations on every
backend.
Probably not the most efficient implementation, but works.
Issues:
* Doesn't seem to render until the second frame. No clue why, yet.
* Hardcoded 640x480 in more places.
* Creates new FBOs for every subpass every frame. Should be done at Framebuffer build or CommandBuffer build time.
This directory used to contain both the state tracking code for the
backends, and the common utilities that could be used both by the
backends and the rest of the code. Things are now:
- src/common is utility code for the whole repo
- src/backend contains libNXT's code
- src/utils is utility code that we don't want in libNXT
This commit also changes all includes to use global paths from src/
bacause it had to touch a bunch of #include statements anyway.
No functional changes intended, but there are a couple additional
cleanups:
- Use anonymous namespaces instead of static functions
- Don't store an extra Device pointer in objects
