Try using a different align. ALIGN_NULL means you have full freedom to drag in any direction.

I know. But it is what I want. Anywhere in view area begin and anywhere end. Problem is only, that I want restricted position of end to border of view, but now there is restriction to right and bottom only. I solved it by simply modification of RectTracker::MouseMove

if(tx == ALIGN_NULL) {
	rect.right = min(org.right - op.x + p.x, maxrect.right);
	if (rect.right < rect.left) {
		Swap(rect.right, rect.left);
		rect.InflateHorz(1);
	}
}

to:

if(tx == ALIGN_NULL) {
	pom.x = min(org.right - op.x + p.x, maxrect.right);
	rect.right = max(pom.x, maxrect.left);
	if (rect.right < rect.left) {
		Swap(rect.right, rect.left);
	}
}

But it is not clear enaugh. There are variations of +-1 pixel depending of draw direction.
Now it's adequate for me, but not as final solution.

Thanks for interest.
