+/**
+ *  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 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:
+ *
+ * 1.2.1, 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
