[Octave-bug-tracker] [bug #31100] patch edges always black with fltk backend

[David Bateman]

Update of bug #31100 (project octave):

                  Status:                    None => In Progress            
             Assigned to:                    None => dbateman

Follow-up Comment #2:

While looking at the slow contour bug report I figured out why this is
happening. The fltk backend is misinterpreting the sense of the
facevertexcdata property. It is using the facevertexcdata property to set the
edge color, whereas 

http://www.mathworks.com/help/techdoc/ref/patch_props.html

states clearly that this affects the facecolor. The __patch__ fucntion in
octave sets this value accordingly, and often to [] which results in the fltk
backend plotting black edges for the patches. The fltk backend should use the
"edgecolor" property instead to set the color of the patch edge.

As I'm working on this stuff now, I'll fix this issue.

D.
