* shrinkfaces_04: shows "inverted?/outer faces", completly different from matlab
* [http://tech-chat.de/compare_plot_demos/gnuplot/colorbar_23.png gnuplot] + [http://tech-chat.de/compare_plot_demos/fltk/colorbar_23.png fltk] colorbar_23: xtick unreadable. It should check the text_extent and reduce xticks if the xlabels would overlap.
* text_03: can't print multi-line text objects [http://savannah.gnu.org/bugs/?31468 bug#31468]
 
* colorbar_20: Latex label 10^{2}, 10^{1.5} not in print output. See bugs #42988, #42320, #42340 which are mostly duplicates
* [http://tech-chat.de/compare_plot_demos/gnuplot/colorbar_01.png gnuplot] + [http://tech-chat.de/compare_plot_demos/fltk/colorbar_01.png fltk] colorbar* : This is just a matter of taste but I (Andy1978) would prefer a  smaller gap (only 40% of the current implementation?) between colorbar and the plot like [http://tech-chat.de/compare_plot_demos/matlab/colorbar_01.png matlab] does.
 
* [http://tech-chat.de/compare_plot_demos/fltk/colorbar_19.png fltk] colorbar_19.png : unusable colorbar with FLTK ([http://savannah.gnu.org/bugs/?42311 bug#42311]) when log scale is set, fine with [http://tech-chat.de/compare_plot_demos/gnuplot/colorbar_19.png gnuplot]
 
* gnuplot + ftlk: fill_01, fill_02: hidden edges keep visible in ML, not with fltk or gnuplot. This seems to be a ML bug when printing to PNG or JPEG and works (same output like gnuplot+fltk) when printing to ps. In FLTK the on-screen images shows the hidden edge and becomes invisible when printing.
 
* [http://tech-chat.de/compare_plot_demos/gnuplot/hold_07.png gnuplot] + [http://tech-chat.de/compare_plot_demos/fltk/hold_07.png fltk]: hold_07: red rectangle hides the '^' plot markers. In ML they disappear on-screen as soon as xlim is changed or zoomed. Is this a ML bug? What is the prefered behaviour?
 
* [http://tech-chat.de/compare_plot_demos/gnuplot/shrinkfaces_04.png gnuplot] + [http://tech-chat.de/compare_plot_demos/fltk/shrinkfaces_04.png fltk] shrinkfaces_04: shows "inverted?/outer faces", completly different from [http://tech-chat.de/compare_plot_demos/matlab/shrinkfaces_04.png matlab]
 
* [http://tech-chat.de/compare_plot_demos/fltk/text_03.png fltk] text_03: can't print multi-line text objects [http://savannah.gnu.org/bugs/?31468 bug#31468]

* gnuplot + fltk compass_01: no proper scaling/zoom: A changeset from Stefan Mahr fixing a different part of polar() also solves the auto-scaling issue with compass().  See http://hg.savannah.gnu.org/hgweb/octave/rev/cff49c82f722.
 
* The right axis of the [http://tech-chat.de/compare_plot_demos/gnuplot/pareto_01.png Pareto plot] was being drawn in a different color from the left axis. http://hg.savannah.gnu.org/hgweb/octave/rev/f1e21a495e20
 
* [http://tech-chat.de/compare_plot_demos/matlab/patch_04.png gnuplot] + [http://tech-chat.de/compare_plot_demos/fltk/patch_04.png fltk] patch_04: the demo incorrectly assumes the patch "facecolor" is "flat" as octave currently sets this by default (whereas in matlab "facecolor" is "none" by default). This should be fixed with [http://savannah.gnu.org/bugs/index.php?42159 bug#42159] (this probably is also the cause for black faces in shrinkfaces*)

* fltk/ML axis_09, axis_10, axis_11, axis_12, axis_13:  No, [x,y]axislocation' 'zero' (http://savannah.gnu.org/bugs/?40588). This is an Octave (and gnuplot) only feature. We can either blacklist, or visually skip over the comparison since it is blank for Matlab. Perhaps should be removed from demos or blacklist axis_09 in dump.m script
