NOTES:
- Microsoft's C compiler doesn't support certain C11/C99 features, such as VLAs
- tinyvk/tinydx is written for experimentation and fun-having - not performance
- For simplicity, only one descriptor set can be bound at once
- In D3D12, this means two descriptor heaps (CBVSRVUAVs and samplers)
- For Vulkan shaders the 'set' parameter for 'layout' should always be 0
- For D3D12 shaders the 'space' parameter for resource bindings should always be 0
- Vulkan like idioms are used primarily with some D3D12 wherever it makes sense
- Storage buffers created with tr_create_storage_buffer are not host visible.
- This was done to align the behavior on Vulkan and D3D12. Vulkan's storage
buffers can be host visible, but D3D12's UAV buffers are not permitted to
be host visible.
