Software Screen to Screen BitBlt Acceleration GRADD filter, r0.0.1

Long Description:
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 using 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, in order to eliminate unnecessary and much slower peripheral bus cycles. Typically, such slower software BitBlts may speed up to x1.5 ~ x2.5. Highly recommended for GENGRADD / poor-accelerated GHI (such as M64GRADD in 24bpp) users.
