Specifies the origin of transformation used by transformation behaviors and animators such as Move, Scale, Rotation, Scaling, etc.

The possible values are:

• Center (default) Transforms originate at the center of the element.
• TopLeft Transforms originate at the top left corner of the element.
• Anchor Transforms originate around the point specified by the Element.Anchor property.
• HorizontalBoxCenter Simulates the effect of the element being the front-facing side of a cube in 3D space, using the width of the element for determining the depth of the cube. Without the element being in a Viewport this will have no illusion of depth, effectively rendering it useless.
• VerticalBoxCenter Like HorizontalBoxCenter except it uses the height of the element for determining depth.
