Some scrollwheel-related patches for 4.8

[Erik-Jan]

Hi,

Congratulations (and celebrations) on the release of 4.8!

I've updated my invert-workspaces-scroll-direction patches for the new 
version.
One patch for xfce4-panel (scrolling on the pager), and one for xfwm4 
(scrolling on the background).
You can find them here:
http://bugzilla.xfce.org/show_bug.cgi?id=3361

And I've made a new patch. It prevents raising an unfocused window when 
you only scroll on it. Using any other mouse button still raises the window.

The functionality of these patches have been discussed (years) before, 
see Bugzilla. Inclusion in mainline is not really a goal. For me they 
are just useful, and sharing the code maybe helps someone else as well.

Bye,
Erik-Jan
