[Octave-bug-tracker] [bug #44735] OpenGL patch outline has incorrect Z depth with respect to other patch fill colors

[Pantxo Diribarne]

Follow-up Comment #6, bug #44735 (project octave):

The sample code from comment #4 now works like in Matlab, i.e there is no
overlapping line, but the original issue remains. 

The opengl renderer doesn't use depth sorting anymore when drawing pure 2D
plots. For patches drawn one after the other (see comment #4) this works well
since each outline is drawn right after its corresponding fill content. In the
original example there are 2 faces in one patch so the fill content is drawn
first (with 2 colors) and the outlines after.
