Follow-up Comment #8, bug #44111 (project octave):


@Rik: maybe we used to but AFAICS we currently don't use
GL2PS_POLYGON_OFFSET_FILL. If I modify gl2ps-renderer this way:

diff -r fd9a5da4afff libinterp/corefcn/gl2ps-renderer.cc
--- a/libinterp/corefcn/gl2ps-renderer.cc       Tue Feb 03 12:51:54 2015 +0100

           if (ret == GL2PS_ERROR)
             error ("gl2ps-renderer::draw: gl2psBeginPage returned
           old_print_cmd = print_cmd;
+          gl2psEnable (GL2PS_POLYGON_OFFSET_FILL)
           opengl_renderer::draw (go);

The following scripts renders the colorbar perfectly:

sombrero (); colorbar (); print -dpng toto.eps

So it looks like a very good idea Rik. Am I correct that we unconditionally
want to use this feature (BSP sort or not)? Should I go ahead with this
