       Short Description: Software Screen to Screen BitBlt Acceleration GRADD filter, r0.0.5

        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 by its own faster blitter rather than

                          default SOFTDRAW engine.

                            - 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.
