Follow-up Comment #7, bug #49260 (project octave):

I expanded the code in the demo for autumn to better show how gnuplot is
getting the Z-depth stacking wrong between the axes object and axes children.

close all
graphics_toolkit gnuplot
cmap = autumn (256);
h = rgbplot (cmap);
set (h, "linewidth", 5);
print -dpsc2 cmap.ps

As you can see in the attached Postscript file, the axes layer is either on
top, or maybe it is being alpha blended with the line objects from rgbplot.

The second Postscript file is after doing

graphics_toolkit (1, "fltk")
print -dpsc2 cmap2.ps

(file #38679, file #38680)
