Yes, you're right : I've tried that already and it's pretty fast...
Although drawing inside images offers more possibilities :
resizing, rotating, blending, exporting...
Furthermore, polygons (and graphics in general) don't have
antialiasing in Rev yet (although it's a feature that some list
members have been asking for since 2001) and the display
can sometimes look ugly...
