Hey,
Got it solved. I was right when I guessed the resolutions were
different, even though I didn't know what I was talking about. When I
created the bitmap cgcontext, I made it take up the whole screen and
then drew it to a view that was smaller, thus the squishing. I thought
for sure it would be because the points weren't being converted
correctly....
