WARNING: This method should never be used to apply a new
coordinate transform on top of an existing transform because the
Graphics2D

needed for other purposes, such as rendering Swing
components or applying a scaling transformation to adjust for the
resolution of a printer.
To add a coordinate transform, use the

or shear
methods. The setTransform
method is intended only for restoring the original
Graphics2D
