[Usability]Some questions about the Gnome canvas

[Jean Bréfort <jean brefort ac-dijon fr>]

Hi,

I hope this list is the right one for my questions.

* The GnomeCanvasRichText item is not implemented in the anti-aliased 
canvas. Why? I don't understand what might be the problem.

* In GnomeCanvasLine, PROP_SMOOTH and PROP_SPLINE_STEPS are declared but 
not implemented. These would be probably very useful for me in 
GChemPaint since I need curved arrows.

* Also in GnomeCanvasLine, ther is no PROP_DASH as exist in 
GnomeCanvasShape. I think it would be easy to add it. Using 
PROP_LINE_STYLE to draw dashes is not as versatile (and, anecdotically, 
double dashes appear the same as solid line on my screen).

Best regards,
Jean Bréfort
