[Octave-bug-tracker] [bug #30564] Can't draw five- or six-pointed star, left or right triangle markers on plots

[Ben Abbott]

Follow-up Comment #5, bug #30564 (project octave):

After a bit of googling, I learned that OpenGL can only draw convex polygons.
Fortunately, the vertices for these concave shapes may be ordered to that the
restrictions of OpenGL will properly render their concave shape.

I've attached a modified changeset (changeset-fltk-2.patch) and pictures of
the oversized markers with the reordered vertices.
