I am currently evaluating DotAnnotate 6.0 via the "Annotation Demo" and had a couple of questions:

 1.  To resize an object such as an embedded image, you grab a grip and move it.  One corner is anchored while the other corners move to new size positions.  Can you change the behavior so that resizing is done from the center?  In other words, the center point is anchored while all corners are moved simultaneously?

 2.  I noticed that when resizing an object like in the previous scenario, a seemingly random corner is picked as the anchored corner.  How is the anchor corner determined, and is it configurable?

 3.  To rotate an object, you grab the green dot and move it.  Can I eliminate the green dot and grab a corner or edge grip instead to do rotations?  Can I define my own hotspot that is used as the grip for rotations?
