README

General
=======
This is a part of visvis library [1], specifically visvis.vvmovie.
The files are from the visvis-1.8 version.

[1] https://code.google.com/p/visvis/

Changes
=======
In images2avi, the image format for temporary files is changed
from JPG to PNG, to improve the resulting AVI. This makes the size larger,
however the JPG format is unsuitable for maps in general.

Questions
=========
Should we make these files PEP8 compliant? This would make
merging of possible changes from visvis more difficult.
