copy TA_GLOB_TILE_CLIP and SCALER_CTL to rend context when starting
render. Use rend context copy to calculate framebuffer size.
Fixes framebuffer size glitches in vf4 water stages.
lr: pass aspect ratio when resizing.
dx11: Wrong sizing of rotated games.
gl: test automation fixes.
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.
Use RETRO_ENVIRONMENT_SET_SYSTEM_AV_INFO or
RETRO_ENVIRONMENT_SET_GEOMETRY to report resolution/aspect ratio
changes.
Handle rotation without restarting.
