gimp/plug-ins/common/qbist.c
Jehan 90f8cb54eb plug-ins: fix crash of qbist when loading files. 
Contents of these arrays are assumed to be limited to a specific range.
While it did work sometimes (because a further processing would randomly
regenerate some of the indexes and correctly limit the range), it often
crashed.

This commit fixes the crash, but I am not sure this plug-in is working
exactly as expected regarding data load/save. It feels like you would
expect to always get the same patterns with a same source data. Yet
there is further randomization going on.

Oppositely when saving data, and re-loading it later, I would expect
once again to get back the exact same patterns I had when saving the
data. So it would be a way to save the result of randomization (as
chances to get back a pattern one liked are slim by definition when it's
created randomly).

Right now, it doesn't behave at all like this. Files are only used as
some kind of random seed, not as a way to save/load patterns. I feel
this was not the purpose of the file handling here.

* It appeared in c't 10/95, page 326 and is called
* "Ausgewürfelt - Moderne Kunst algorithmisch erzeugen"
* (~modern art created with algorithms).
*
* It generates one main formula (the middle button) and 8 variations of it.
