hatch.py could use some integer vs. float division clarification

[argriffing]

I'm not brave enough to try figuring out which variables are actually supposed to be integers, especially because it's graphics so testing might not be as straightforward, but eventually numpy will balk at float indices. The from __future__ import division is causing many variables in that module to be floats.

Could be fixed in #3241.

I think this is cleaned up by #3241 as it got everything that was actively complaining.

Please open a new issue if there are specific cases that need to be fixed.
