New issue 265 by nico...@pyryp.com: PMouseWheelZoomXYEventHandler : I can not commit (403 Forbidden)
https://code.google.com/p/piccolo2d/issues/detail?id=265

Hello,

I coded a new class but can not commit it. (403 Forbidden)
Please, would you like to commit it to the SVN.

Thanks,
Nico

Here is the commit message :

* This commit bring a new class, the PMouseWheelZoomXYEventHandler which is a evolved zoom event handler. The default behavior is the same as the existing PMouseWheelZoomEventHandler but 2 other behaviors are available : -> If the user maintains the "SHIFT" key during mouse wheel motion, only the X axis will be rescaled. -> If the user maintains the "ALT" key during mouse wheel motion, only the Y axis will be rescaled. NB : With the default behavior, the zoom will be applied on X and Y axis (as PMouseWheelZoomEventHandler).

 * Somes changes are necessary in the following classes :
    1) PCamera
       --> adding the method
public void scaleViewAboutPoint(final double scaleX, final double scaleY, final double x, final double y)
       --> updating the method
public void scaleViewAboutPoint(final double scale, final double x, final double y)
    2) PMouseWheelZoomEventHandler need to be inheritable.
       --> removing the "final class"
       --> scaleFactor is now protected
--> private Point2D getViewAboutPoint(final PInputEvent event) is now protected
    3) PAffineTransform
       --> the method
public void scaleAboutPoint(final double scaleX, final double scaleY, final double x, final double y)
           has been added.
       --> the method
public void scaleAboutPoint(final double scale, final double x, final double y)
           has been modified.
Please note, that all these changes are fully compatible with the previous version.
