Fall back to 8888 format.
tentative fix for MINIDUMP-17, MINIDUMP-1R and MINIDUMP-1M
RenderFramebuffer wasn't working if first render after init.
ImGui is now initialized once at startup and shutdown before

Move more imgui stuff into imgui drivers.

UI scaling refactoring.
libretro: Null first frame erroneously set as valid causing a crash with dx11 (single-threaded rendering)
libretro: pass dx11 compiler pointer to shaders
dx11: use feature level to check if per-pixel is supported
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)
