Well, GTK is notorious for killing features. Ada is much less so, in 
that sense, yes.

Vector graphics especially as limited as described in the document is of 
minor interest compared to proper 2D graphics: UI windows, widgets, 
controls. So if you want to start begin with the latter. (:-))

P.S. Many embedded platforms would rather use raster graphics instead of 
the vector one, for obvious reasons. ARM rendering performance is just 
horrific, literally.
