setMaxScale and setMinScale not working.

[GoogleCodeExporter]

Hi Team,
I am first time user, so I tried to achieve with my limited knowledge.
Basically facing 2 issues:
1. restricting Max and Min size of zooming does not work with 
PMouseWheelZoomEventHandler
2. Canvas look is shrinking for repeated Zoom IN/OUT using mouse wheel, (like 
zoom in one step then zoom out one step, repeat...)

What steps will reproduce the problem?
1. Used the MouseWheelZoomExample and added 
mouseWheelZoomEventHandler.setMinScale(1.0d);

        // install mouse wheel zoom event handler
        final PMouseWheelZoomEventHandler mouseWheelZoomEventHandler = new PMouseWheelZoomEventHandler();
        getCanvas().addInputEventListener(mouseWheelZoomEventHandler);
        mouseWheelZoomEventHandler.setMinScale(1.0d);

I tried with various values for both Max and Min, but don't see any restriction 
while zooming.
2.
3.

What is the expected output? What do you see instead?
It should restrict upon reaching max and Min value

What version of the product are you using? On what operating system?
1.3.1 Ubuntu 12.4

Please provide any additional information below.

I was trying to set the max and min zoom scale, so need to override the 
mouseWheelRotated() function, which is not completely achievable, then I 
encounter another issue,Zoom-in and Zoom-Out by one step continuously shrinking 
the look and also there is center coordination shift. so in other word, we 
can't get back to original size once mouse wheel zooming option.

To clarify, are you on Piccolo2D version 1.3.1 or on svn trunk (version 
2.0-SNAPSHOT)?  It has been a while since I looked at the 1.3 branch but I 
don't see PMouseWheelZoomEventHandler there.

Yes, I am using Piccolo2d 1.3.1 version with PMousewheelZoomEventHandler 
external wrapper available.

Hello, there aren't setMinScale/setMaxScale methods in 
PMouseWheelZoomEventHandler in Piccolo2D version 3.x on svn trunk; I'm not sure 
how to help further.
