I was thinking in the way of, if convert of Imagemagick is present, then
offer the option/just do it, otherwise not. I know it is fast and good, I
don't know how the gdk manipulation methods fare, nor how they handle
png/jpg/bmp/.... . The other big advantage I was seeing was the fact that we
could do it in other processes, so the web generation can continue without
Obviously, we can make a convert.py, and run that as a separate program too
to do the region clipping, with same advantage of not waiting for the
conversion to finish.
The idea would then be: we have pic.jpg, with handle MOCIR5KCQXECKHKZNI, so
this is in images/M/O/MOCIR5KCQXECKHKZNI.JPG, and we generate
images/M/O/MOCIR5KCQXECKHKZNI_A__B.JPG for every region AxB that is needed.
If already exiting, then don't regenerate (important as this is in a media
reference, so same region can appear multiple times, we don't need multiple
