Add an option to downscale hi-res views
2020-08-13Add an option to downscale hi-res viewsJustin Weiss
Some older devices that use gpu_unai don't have a high enough resolution to display all of the pixels in high-res mode. There's a setting in unai to skip rendering of these pixels, but it's not connected to the libretro frontend, and does not appear to be used in the gpulib implementation at all. This commit adds a gpu_unai setting, Enable Hi-Res Downscaling, that will enable pixel skipping and blit only the pixels actually rendered into a buffer no larger than 384x240. This buffer is then treated as the actual framebuffer by gpulib and the libretro frontend.

2020-03-01Preserve uSrc MSB across lighting and blendingJustin Weiss
This saves a few cycles because gcc stores / loads srcMSB when using ARM-optimized lighting.

2011-08-13gpu_unai: fix inline asm statementsnotaz
newer gcc reorders them and was allocating registers wrong due to incomplete constraints. Not that this code is any better than what gcc generates anyway, but whatever.
