Uhmmm am I wrong or svg is done simply through the wx print mechanics? in common there are plotting routines only for HPGL, PS and Gerber...

IMHO using wxFont would be a PITA... matching metrics and spacing between screen and plot would be really difficult (thing like hinting and similar stuff). IF we have a 'filled polygon' primitive in wx with a reasonable fill rule (i.e. winding, not odd/even), just feed the outline to it to draw on screen...

In drawtxt there already is a 'sister' plot routine, it shouldn't be too difficult to isolate this thing. BUT we loose the 'text width', because it will then dictated by the font outline.
