Scale the object depending on context, for instance uniformly for a "Circle" figure and non-uniformly for an "Ellipse" figure.
Scale the object in both directions so as to fit exactly in the given bounds; there is no clipping, but the aspect ratio may change, causing the object to appear stretched.
Scale the object as much as possible in the x-axis.
Do not scale the object; there may be clipping in one or both directions if the available dimensions are too small.
Scale the object as much as possible in the y-axis.
This enumeration specifies possible values for GraphObject.stretch.
