Follow-up Comment #31, bug #45494 (project octave):

>> One has to not reassemble the blue triangle to disrupt the hidden-surface
layering. But one could, in fact, include the red rectangle as part of a
tessellation ...

What you are proposing is to apply projection and clipping which looks like a
very hard task for which neither OpenGL tesselator nor gl2ps will help.

Anyway, I just tried again to remove the "GL2PS_NO_PS3_SHADING" option, and
for some reason it worked !(I am pretty sure my conclusion was the contrary a
few month ago ???). I was able to generate all the demos I tried as pdf and
the antialiasing lines are most of the time hardly visible. Can someone else
try the attached patch? 

(file #41332)
