[Octave-bug-tracker] [bug #40054] FLTK: incorrect Z-order stacking for markers and images

[Rik]

Follow-up Comment #6, bug #40054 (project octave):

How does gl2ps handle this?  I just tried the original code, and then flipped
the stacking order, as shown below.


graphics_toolkit fltk;
clf;
colormap ('default');
hold on;
plot (1:4, '-s');
imagesc (1 ./ hilb (4));
hold off;
print -dpng bottom.png
kids = get (gca, 'children')
set (gca, 'children', flipud (kids))
print -dpdf top.png


The png files are correct without the artifact of the marker alone being out
of Z-order.

If we were to skip using the Z-delta spacing in 2-D mode, what files need to
be changed?  Is it something easy to try, or a huge re-code?  If small, I'd
like to try it and see if it fixes the problem.
