Subject: logicop problems: FIXED
From: briand at aracnet.com


FIXED !

The problem was the difference between index logic and color logic.
Notice that in the patch logic_op and index_logic_op are actually the
same.  This is as per OpenGL usage.

Simply apply the patch to lablg-1.00.  Rebuild as required.

In my particular case I did 

    make lib; make install

Then make sure and rebuild lablgtk2 !!

Enjoy rgba logical operations :-)

Brian

P.S. I don't supposed lablgl has support for overlay planes, does it ? :-)
