This is pretty close to what I want to do for the buffered (2 bit) pxl library!
After two weeks or so of experimentation, I’ve begrudgingly concluded that the Lee raster subprogram is really the only way to approach a 2 bit version of my direct pxl library. Using the raster interrupt slows down the main program so much! There’s two things I’ll be doing to speed it up though... First, during window setup, provide a parameter for the number of columns to be directly shown on screen without a buffer (uses more cells, but much faster). And second, draw per bit, not per color (same approach as direct pxl library, just with an 8 byte address offset to access the “hi” bytes). This would allow the programmer to decide whether they wanted a “fast” or “slow” draw, rather than the speed of the draw being determined by whether or not color 3 is used.

Im so glad we have one who understands bit math... i REALLY appreciate all you do in that regard :D
