oit: skip to new frame even if previous frame was never presented
libretro: quad pipeline used for overlay must use subpass 2 in per-pixel
overlay: delay destruction of VMUs images
libretro: WaitIdle on queue instead of wait_sync_index
dx11: use 32-bit float depth texture to avoid loss of precision (SA2 into logo)
dx11: cache shader blobs to disk if not provided by OS
dx11: swap interval depends on screen refresh rate (1 for 60 Hz, 2 for 120 Hz, ...)
dx9: use clipping planes to avoid interpolation errors in rasterizer (daytona, mermaid lake)
directsound: use comptr
gui: fix navigation issue with OptionArrowButtons due to missing id
Refactor imgui backend code into imgui drivers for gl, vk, dx9
Generic GraphicsContext interface for gl/vk/dx9 contexts
Simplify graphics api switching code
dx9, gl(sdl): set swap interval based on monitor refresh rate.
Increase descriptor set pool size for combined image sampler to
accomodate for games using a stupidly large number of textures.
Don't use mailbox mode on AMD as it needs 5(!) swap chain images on
linux.
Return to a swap chain size of 3 since it's the min for AMD.
