Take a look at the the 'dashed' line implementation on the object handles code you got. Instead of using actual lines, use a transformed Bitmap with a hole (1-2 pixel inset polygon basically) with a repeated fill - the fill inherits it's transformation matrix from the handles matrix.
I extended the senocular TransformTool code to utilize this in Flex for a recent project and it made much cleaner code and always looks crisp and clean looking.
just a thought.
