The initial version of FvwmForm suffered even more than the core and
other modules with a poor algorithm for selecting shades. I submitted
a patch to it which, amongst other things, adopted the shading algorithm
from TK (John Ousterhout's window environment for TCL) which is one of
the best I've come across it. This patch has been integrated into the
distribution version for quite a while now.
It would be good to move this code into libfvwm as a lot of modules try
and maintain a similar looking 3d effect to the core - common code is
the best way to do it.
I doubt if there's any copyright problems. TCL and TK have very liberal
copyright and we're only poaching about 15 lines of code from it.
