I was thinking that you would have the handles actually *on* the brush,
but as you note in your second mockup, probably it is better to have the
handles away from the brush. In that case, it just means that the box is
the smallest possible containing box, i.e. sides parallel to the major
and minor radii of the ellipse. (Or, more simply, the box is rotated by
the same amount as the brush. In fact, this would be a good idea for
rectangle brushes also...)
On that note, how come we even have separate rectangular and elliptical
brushes, and not just rounded rectangles (where 100% round makes it an

Sounds great to me :-). (I'm not sure what you would draw with a brush
that has a radius of 0.05 pixels though ;-), but maybe/probably such
small values work better with brushes that are effectively lines.)

Hehe, sorry for hijacking the thread :-). I already replied before I
read this, though; maybe someone else (i.e. whoever has read this and
replies next) can start a new thread.
If you can read this, you're too close.
