/**
* isiri2901.user.js - Standard Persian keyboard Greasemonkey script for Firefox
* Converts all textboxes (textareas and text inputs) to english/persian and
* adds a tiny toolbar to switch keyboard.
* Just like the original code:
* Keyboard also switchable using CTRL+ALT.
* SHIFT+SPACE inserts a Zero-Width-Non-Joiner character.
*
* Since by default this is enabled for all sites, the isiri2901_lang variable
* in the original code to set to English by default.
*
* Copyright (C) 2007 Hooman Baradaran
*
* Based on:
* isiri2901.js - Standard Persian keyboard driver for JavaScript
* (Code and copyright notices attached below the Greasemonkey-specific code)
*
* Notice that the above code is included below with no change. That is why
* there is some IE related code. In fact the original script was made for IE
* and change to support Mozilla/Firefox later.
*
* ChangeLog:
* Mar 22, 2007 Hooman Baradaran, renamed simply "Iranian Keyboard" + bug fix.
* Mar 21, 2007 Hooman Baradaran, small text box and toggle button added.
