Thanks, Tristam. I tried all that, and double-checked my math, but it still looked a little off.
I was just able to fix it, though. The problem was in my cocos2d initialization. I apologize for not mentioning I was using that library in my original post. I started looking at the cocos2d director code after exhausting the other options, and realized it was scaling the projection matrix. I added `do_not_scale=True` to the director instantiation, and the sprites are now being drawn without any "blurriness".
