	I have some questions on the dynamic hires/ham modes:

	1.  If I understand correctly, DHR uses a standard HiRes (640 width)
screen, but changes the palette eveney line to give more colors.  My question:
why change the palette only once per line?  I've seen demos that change
palettes every eight pixels (hires copper resolution sucks!), so why can't DHR? 
Is it because it has to change all 16 colors?

	2.  How, exactly does DHA work?  How come I never see anything that
uses it?  My guess: it changes the palette when necessary to eliminate the
fringing effect of HAM.  If this is true, wouldn't this be better in some ways
than DHR?

	Also, what are the chances of C= ever introducing an upgraded copper
chip (faster=higher horiz. resolution, I THINK)?  Wy guess would be NEVER,
because all previous programs that used copper lists would be totally messed!
