	I got it!  The tiles were on uneven coordinates on the texture
page, since there were gridlines separating them, and someone from
SCEE told me this.  I didn't know that GsBG tiles had to be on odd
coordinates, so I edited the graphics and it's fine now.
	Mario told me about sprites and he said 4096 doesn't always
work, use 4095 instead, and it did work -- it was only noticable on
sprites with thin lines -- the scaling causes those lines to "blink
out" for some unknown reason!  
	This kind of stuff should probably be posted on a FAQ.  I'll
try to work on coming up with a lot of yaroze stuff I've learned in
the past, so that people don't have to get hung up on silly stuff like
this.
