BitBlt raster opcodes calculated?
The complicated language of raster operation codes.
Adding features by removing code.
Because that's where we last left it.
The ultimate in backward compability.
The generic function pointer.
The computer itself ceases to exist.
But flukes can happen.
Universality is not universal.
True each time it is uttered.
BitBlt by generating code on the fly
Artisanal bit block transfers made to order.
