How do I draw an ellipse (or rectangle, for that matter), rotated by some angle? I know about Drawable::draw_arc() and draw_rectangle(), but these only draw the objects with the semiaxes parallel to the image axes. I imagine I have to set up some transformation matrix, and I don't know what to look for. Thanks!
You either need an some 3D graphics system (e.g. OpenGL) or manually break the shape into little segments and draw them individually.
I guess the former is easier. Ben
