I'm implementing new CopyArea code for the R4 server which speeds up non GXcopy-mode bitblt for both color and monochrome frame buffers. But, I have no applications which do non-copy blt and I'm looking for some input. I need to know how applications are using non-copy mode bitblt, both the raster ops and whether non-trivial planemasks are used. Given this, I can optimize, in a relatively space-efficient manner, each commonly used combination. Keith Packard MIT X Consortium
