[Octave-bug-tracker] [bug #54690] surface/patch markers not clipped to axes with OpenGL toolkits

[Pantxo Diribarne]

Update of bug #54690 (project octave):

                 Summary: markers not clipped to axes with OpenGL toolkits =>
surface/patch markers not clipped to axes with OpenGL toolkits 

    _______________________________________________________

Follow-up Comment #3:

@Rik: Matlab also renders markers if their coordinates are exactly on  the
limit (see e.g. datetick_02.png in
https://josoansi.de/octave_plot_compare/compare_plot_demos_02.html), so Octave
behaves as Matlab for line objects. 
The problem here is specific to surface and patch objects for which markers
are never clipped. Changing the title again. 

The simple test case is 


clf
patch ("marker", "o", "markerfacecolor", "r", "clipping", "on")
xlim ([.05 .95])


There is already some logic for clipping but it simply doesn't work.
