bad path exception

[Jorg Heymans <jh...@domek.be>]

Hi,

I was playing around with the zooming interactor and found that when i 
zoomed to a really small rectangle i am triggering following exception :

sun.dc.pr.PRException: endPath: bad path
atsun.dc.pr.Rasterizer.endPath(Rasterizer.java:537)

The canvas seems to go confused afterwards. It seems that it's not 
repainting parts of the viewbox anymore (not consistenly reproducable 
though). Zooming out restores everything again back to its normal state.


Thoughts?
Jorg

    This is a known issue with the Java2D renderer if the scale factor
get's too large it goes out to lunch.  One might choose to limit
the scale factor to something reasonable.

    The Java2D renderer doesn't work right at scales like that.
