not really, unfortunately.  xfdesktop uses MCS for all its settings, so there
isn't a handy file you can append something to like for xfwm4.  i suppose
you could add a hidden MCS setting, but that would mean that you'd need to
add/change the pref without the mcs manager running (to be safe).

as danny pointed out, the callback that handles the scroll event is in
src/main.c (i think it's called button_scroll_cb() or mouse_scroll_cb() or
something).  i don't believe the McsClient is very well exposed in main.c,
so it might be somewhat difficult to logically organise it.

personally, i'm not convinced that this is a necessary option to have.  i
understand the problem you have, but i'm somewhat reluctant to add something
like that to xfdesktop.  you can make up a patch for it, but don't be
surprised if i don't commit it (though, if it's not too much work, i might
mess around with it a bit).
