Okay, so I was a bit bad about committing lately, but here's the low-down
(I think):
- Lots and lots of debugging on the painting model. Pretty sure it has a
  few patchwork fixes here and there, but it does seem to work as needed.
- MovieActivity (and the MainActivity, also) seem to be working as
  expcted, other than persistence is sketchy, and some layout should be
  addressed.

Next job is probably getting persistence to work, then layout and
(hopefully) getting icons on buttons rather than ugly ass text that
dosen't work well.
