Image annotation UX improvements

As an annotator, you can more easily create a rotated bounding box with a "three point" or "two point" click for image annotation:

• First point click - Starting point of the location to draw the bounding box.
• Second point click - Define the rotation and width of the bounding box.
• Third point click - Draw the height of the bounding box.

After you create the bounding box, you can adjust it by moving the anchors or edges to the desired location on the image.
