Hi Igor,
The new functions are:
virtual void drawPolygon( const std::vector<std::pair<float,float> > &cds )
= 0;
virtual void drawEllipse( const std::pair<float,float> &cds1 ,const
std::pair<float,float> &cds2 );
I've done drawPolygon() already but haven't tested it. The second does not
*need* to be implemented (there is code that simulates it if it's not
present), but it certainly makes things faster if it's there.
The other change that would need to be made is to support the toggling of
filled polygons in drawPolygon, drawTriangle, and drawEllipse. Here's how
the cairo drawer handles it:
