 *
 * Version 1.22 - March 30, 2009
 *   - Added support for max-length on inputs (Olivier D??sormeaux)
 *   - Downgrade comma-below forms of S and T to cedilla for IE < 8
 *   - Change exposed attachment function name to VKI_attach
 *   - Exposed keyboard close function as VKI_close
 *   - No longer expose any functions in the userscript version
 *

    // - Lay out each keyboard in rows of sub-arrays.  Each sub-array
    //   represents one key.
    // 
    // - Each sub-array consists of four slots described as follows:
    //     example: ["a", "A", "\u00e1", "\u00c1"]
    //
    //          a) Normal character
    //          A) Character + Shift or Caps
    //     \u00e1) Character + Alt or AltGr
    //     \u00c1) Character + Shift or Caps + Alt or AltGr
    //
    //   You may include sub-arrays which are fewer than four slots.
    //   In these cases, the missing slots will be blanked when the
    //   corresponding modifier key (Shift or AltGr) is pressed.
    //
    // - If the second slot of a sub-array matches one of the following
    //   strings:
    //       "Tab", "Caps", "Shift", "Enter", "后退", "Alt" OR "AltGr"
    //   then the function of the key will be the following,
    //   respectively:
    //     - Insert a tab
    //     - Toggle Caps Lock (technically a Shift Lock)
    //     - Next entered character will be the shifted character
    //     - Insert a newline (textarea), or close the keyboard
    //     - Delete the previous character
    //     - Next entered character will be the alternate character
    //
    //   The first slot of this sub-array will be the text to display
    //   on the corresponding key.  This allows for easy localisation
    //   of key names.
    //
    // - Layout dead keys (diacritic + letter) should be added as
    //   arrays of two item arrays with hash keys equal to the
    //   diacritic.  See the "this.VKI_deadkey" object below the layout
    //   definitions.  In  each two item child array, the second item
    //   is what the diacritic would change the first item to.
    //
    // - To disable dead keys for a layout, simply assign true to the
    //   this.VKI_layoutDDK (DDK = disable dead keys) object of the
    //   same name as the layout.  See the Numpad layout below for an
    //   example.
    //
    // - Note that any characters beyond the normal ASCII set should be
    //   entered in escaped Unicode format.  (eg \u00a3 = Pound symbol)
    //   You can find Unicode values for characters here:
    //     http://unicode.org/charts/
    //
    // - To remove a keyboard, just delete it, or comment it out of the
    //   source code
