SPRITE DRAW ROUTINES
We draw a series of small tiles ("chunks") together to
create each big sprite. The spritemap rom provides the lookup
table for this. The game hardware looks up 16x16 sprite chunks
from the spritemap rom, creating a 64x64 sprite like this:
0 1 2 3
4 5 6 7
8 9 10 11
12 13 14 15
(where the number is the word offset into the spritemap rom).
It can also create 32x32 sprites.
NB: unused portions of the spritemap rom contain hex FF's.
It is a useful coding check to warn in the log if these
are being accessed. [They can be inadvertently while
spriteram is being tested, take no notice of that.]
Heavy use is made of sprite zooming.
