GIF Export messes up colors sometimes #57
Description
Here's the framework's GIF export of the new Dr. CYL game (https://github.com/chandlerswift/drcyl).
The color of the virus in the second column gets messed up while pills are falling. I appear to have done some antialiasing around the viruses (though this is slated to be fixed as I update the spritesheet) which possibly exhausts the color table? The "real game" doesn't do this; it's just visual artifacts in the exported GIF.
