Hack to fix movie crasher

A movie larger than the max texture size would be rendered - at its original
size - onto a smaller texture, causing an access violation.  This just ignores
the max texture size for movies.

Two better solutions:
1. Resize the movie to the texture size.  Ideal, but slow in my experiments.
2. Don't load the movie texture at all in this case.  A possibility in the
   future, but will require some refactoring first.
