Hey all,
This is a patch that adds desktop switching via the mouse wheel when
you wheel over the pager, just like XFCE4 and recent Gnome versions.
It's my first development with e17, so if I need to fix anything up,
just let me know.
'grats to everyone who put together the EFL, as it was very
straightforward to write this.
