/**

* ext-storage.js
|
*
|
* This extension allows automatic saving of the SVG canvas contents upon
|
* page unload (which can later be automatically retrieved upon future
|
* editor loads).
|
*
|
* The functionality was originally part of the SVG Editor, but moved to a
|
* separate extension to make the setting behavior optional, and adapted
|
* to inform the user of its setting of local data.
|
* Dependencies:
|
*
|
* 1. jQuery BBQ (for deparam)
|
* @license MIT
|
*
|
* @copyright 2010 Brett Zamir
|
* @todo Revisit on whether to use $.pref over directly setting curConfig in all
|
* extensions for a more public API (not only for extPath and imagePath,
|
* but other currently used config in the extensions)
|
* @todo We might provide control of storage settings through the UI besides the
|
* initial (or URL-forced) dialog. *
