I'm fiddling around with the lrectwrite() function to try to make the
alpha component of the color values work correctly. No combination of
zfunction(), zwritemask() and zbuffer() seems to work for me, so my
question is how should I set the state of GL to make the alpha
component work? And how is the alpha component connected to the level
of transparency (is 0x00 or 0xff complete transparency?)?

What I want to do is basically have a cursor drawn, over the 3D
graphics, in PostDraw() with some completely transparent areas.

Regards,
Morten Eriksen
