It does it in a super dirty way, trad renderer needs a massive
refactoring.
It also displays patched skybox, however, we need it to display the
oridingal one.
Now:
- Not necessarily vulkan-specific cvars are prefixed with `r_`
- Vulkan-specific but not RT-specific things are `vk_`
- RT-specific are `rt_`
Fixes#632
Traditional renderer operates in sRGB-γ space (as everyone was in 199x).
Making vulkan textures explicitly SRGB for RT renderer breaks color for
trad rendere. Make sure trad renderer still has raw SRGB-unaware texture
sampling.
Adds an UNORM image view for all relevant SRGB textures, and uses them
exclusively for trad renderer. RT still gets proper SRGB views.
Also rename XVK_ to R_Vk for images
On Windows we're seeing a max size = 0x0 swapchains. Those cannot be created or used. Make sure that we're not, and we're not trying to draw anything when there's no swapchain available.
Unfortunately we still have to call some rendering functions (without actually rendering anything) to make sure that various invariants hold.
fixes#463
Consolidate VkCommandBuffer management into a single entity. (somewhat
done for framectl, not done for staging)
Make sure that we pass enough metadata to be able to timestamp scopes in
cmdbuf.
It does compile, but it won't work: not all init code paths are used.
Also, there are many changes, so other failure modes are totally
possible.
