It sounds like the code that transforms the clip does not detect if the
rectangle is empty first. The clip should be set to a no-area clip if
the incoming width or height are negative (or 0)...

Hello 2d team,
I have a question about clipping in our implementation of SunGraphics2D.
Currently if I set usrClip to Rectangle(100,100,-100,-100) the real clip
will be clipRegion = 100,100,100,100;
But if I set clip to Rectangle2D with the same coordinates the real clip
will be clipRegion = 0,0,100,100;(This is because we normalizes usrClip
before use).
We automatically convert usrClip from Rectangle to Rectangle2D, if our
graphics is scaled. So we get different clipRegion depending from scale.
What behavior is correct? Should we always normalize usrClip before use
or should we treat it as empty/nonexistent rectangle?
