This is a small filter GRADD driver that can intercept some sort of 'Screen to Screen' BitBlt software emulation responses from GHI layer, and will process such responses by its own faster blitter. - both source and destination are VRAM - source-copy raster operation, with no pattern, no transparency, no stretching and no clipping This simple, assembler- coded, MMX / SSEint-ready blitter is heavy optimized for uncached memory reads and write-combined memory writes, designed in order to eliminate unnecessary, much slower peripheral bus cycles as much as possible. Typically, such slower software BitBlt emulations may speed up to 1.5x ~ 2.5x. Highly recommended for GENGRADD or poor-accelerated GHI (such as M64GRADD in 24bpp, INTGRADD and so on) users.
