I was thinking about this issue a bit.
Would not it be better instead of ALIGN_NULL to allow negative "MinSize" ?

Well I chose ALIGN_NULL because I was trying to keep it in line with the rest of the API and make it as unintrusive as possible.
But anything will do. I just want it to work right. Right now I'm using a slightly "hacked" version of RectTracker, which might become a private ShapeTracker before the next release, because I don't want to have to change things every time I download a new U++.
This class has to cover the following points:
1. Allow full mouse movement
2. Be uniform in it's interpretation of coordinates. Current rect tracker doesn't seem to be.
3. Be precise. Again, not the case with current. An experienced user will get annoyed very quickly when they have to drag the mouse one extra pixel depending on the quadrant to align some stuff.
And in the future, I'll need it to track arrows, so that you can visually design relationships between objects. Nothing fancy, just a line with a small arrow head.

. Couldn't one use just simple DrawRects with NOTXOR drawing mode? I'm asking because I'm implementing custom dragable shapes.
