*
* CHANGELOG:
* v0.12 15.9.1997
* Got rid of the unportable snprintf. Also made some _tiny_ GUI fixes.
*
* v0.11 20.7.1997
* Negative values in the matrix are now abs'ed when used to weight
* alpha. Embossing effects should work properly now. Also fixed a
* totally idiotic bug with embossing.
*
* v0.1 2.7.1997
* Initial release. Works... kinda.
*
*
* TODO:
*
* - remove channels selector (that's what the channels dialog is for)
* - remove idiotic slowdowns
* - clean up code
* - preview
* - optimize properly
* - save & load matrices
* - spiffy frontend for designing matrices
*
* What else?
*
