poor compiz default for mouse wheel.

[Stephen Kennedy]

Mouse wheel to change desktops is really bad, especially for laptop
users if they
have the drag-at-edge == scroll == mouse wheel.

Even worse, you can't change the setting with the default install - a
little googling
eventually led me to "ccsm". New users shouldn't have to deal with this hoopla.

Stephen.

PS. apart from that, the beta looks great - subjectively feels much faster on my
machine than 7.10, even with eye candy enabled.
