 * Source dimensions are the assumed dimensions of the  original image.  Basically they define the
 * scale of the coordinate system.  If not set, the original dimensions of the target image are assumed unless a
 * box is defined.  In the latter case the box will be used to scale down the original and then use those coordinates
 * as source.
