-/**
- *  SVGPan library 1.2.2
- * ======================
- *
- * Given an unique existing element with id "viewport" (or when missing, the
- * first g-element), including the library into any SVG adds the following
- * capabilities:
- *
- *  - Mouse panning
- *  - Mouse zooming (using the wheel)
- *  - Object dragging
- *
- * You can configure the behaviour 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:
- *
- * 1.2.2, Tue Aug 30 17:21:56 CEST 2011, Andrea Leofreddi
- *	- Fixed viewBox on root tag (#7)
- *	- Improved zoom speed (#2)
- *
- * 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

-/**
- *  SVGPan library 1.2.2
- * ======================
- *
- * Given an unique existing element with id "viewport" (or when missing, the
- * first g-element), including the library into any SVG adds the following
- * capabilities:
- *
- *  - Mouse panning
- *  - Mouse zooming (using the wheel)
- *  - Object dragging
- *
- * You can configure the behaviour 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:
- *
- * 1.2.2, Tue Aug 30 17:21:56 CEST 2011, Andrea Leofreddi
- *	- Fixed viewBox on root tag (#7)
- *	- Improved zoom speed (#2)
- *
- * 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
