You presume right, it was a change to the AffineTransform to be given to the
java.awt.Graphics2D
object. This work was carried by org.geotools.gui.swing.ZoomPane widget, which
still exists in the
ext/widgets-swing module. The ZoomPane is not tied to any particular renderer.
JMapPane (or
MapViewer?) could probably extends it and get this feature for free.
