I don't know if RendererUtilities.worldToScreenTransform(...) is reliable. The
mouse coordinates is relative to the coordinate system as defined by
Graphics2D.getTransform(), and Swing put a translation in this transform. The
translation depends on the size of windows border. It may be taken in account
in
the (x,y) value of the Rectangle given by getBounds(), but I'm not sure if it
is
the same translation. A safer approach is to work with the AffineTransform used
with Graphics2D, but I don't know if the streaming renderer keep this kind of
information.
We are in the process of rewriting the renderer from scratch, and this renderer
should provides much better support of CRS and this kind of transforms. But it
may take a few months before we get something.
