/** 
 *  SVGPan library 1.2.1
 * ======================
 *
 * Given an unique existing element with id "viewport" (or when missing, the first g 
 * element), including the the library into any SVG adds the following capabilities:
 *
 *  - Mouse panning
 *  - Mouse zooming (using the wheel)
 *  - Object dragging
 *
 * You can configure the behavior of the pan/zoom/drag with the variables
 * listed in the CONFIGURATION section of this file.
 *
 * Known issues:
 *
 *  - Zooming (while panning) on Safari has still some issues
 *
 * Releases:
 *
 * 1.2.1, Mon Jul  4 00:33:18 CEST 2011, Andrea Leofreddi
 *	- Fixed a regression with mouse wheel (now working on Firefox 5)
 *	- Working with viewBox attribute (#4)
 *	- Added "use strict;" and fixed resulting warnings (#5)
 *	- Added configuration variables, dragging is disabled by default (#3)
 *
 * 1.2, Sat Mar 20 08:42:50 GMT 2010, Zeng Xiaohui
 *	Fixed a bug with browser mouse handler interaction
 *
 * 1.1, Wed Feb  3 17:39:33 GMT 2010, Zeng Xiaohui
 *	Updated the zoom code to support the mouse wheel on Safari/Chrome
 *
 * 1.0, Andrea Leofreddi
 *	First release
