This is just a guess, mind you, and if I'm wrong, please, don't everyone
jump down my throat.

The blitter, (again, I think), is just a device to move chunks of memory
back and forth rapidly; it doesn't actually perform the routines to draw
circles or windows or other graphic objects.  From what you said, the new
Mac graphics chip will actually do all the calculations and plotting routines
on its own, requiring only one short command, leaving the CPU free to 
perform other tasks.
