[Octave-bug-tracker] [bug #41872] fltk: 'patch' object covers grid when printed to image file

[sergey plotnikov]

Follow-up Comment #3, bug #41872 (project octave):

This looks like a problem of sorting when rendering an image with gl2ps. We
chose not to sort primitives of 2D images and according to gl2ps documentation
<http://www.geuz.org/gl2ps/#sec:gl2psBeginPage> they are output in stream in
the order they appear in the feedback buffer.

In case we don't switch off the sorting for 2D images (comment out the line 71
(my cset is 6a4b7ccc60b1) of lininterp/corefcn/gl2ps-renderer.cc) output image
has grid before the patch object.

As to the issue noticed by Ma Jun, it's still there and I'm going to make
another bug report if this wasn't yet reported.
