* Implemented changing the icons size (several ones are supported from

16 x 16 to 64 x 64).
* Changed the layout code to have dynamic padding depending on main icon size.
* Fixed a problem with the "Auto Raise" feature where, when the pad was along
  the bottom, you had to tip the top of the screen with the mouse for the pad
  to raise...
