Hi Sergey,in a previous mail (some minutes ago) I asked you to change
gl2ps-renderer.cc

Could you please try something more?
I would set gl2ps_sort = GL2PS_NO_SORT; for testing because the
description for GL2PS_SIMPLE_SORT (when correctness is not crucial.)
doesn't sound appropriate for us.

Then please remove GL2PS_SILENT and GL2PS_OCCLUSION_CULL and cout the
return value of gl2psBeginPage, perhaps we see an error here?
