rotatedObject: Rotate any 2D object by handle, vertex list, or bounding box

Easily rotate any 2D object: rectangles, ellipses, imrois, xy-coordinates

Rotate any 2D object (specified by its vertices or by handle(s) to an imroi object) by angle theta (in degrees), about any center of rotation.
Create rotated rectangle or ellipse specified by its (unrotated) bounding box.
Specify center of rotation by point, or by corner or centroid of bounding box.
Includes shortcut functions rotateRectangle and rotateEllipse for convenience.
