It does a slower scrolling, the mouse must be moved much more for the same 
movement of the scroller..

I think that this kind of code exists in more than one place in GNUstep (and
probably in some applications, like in mine), because there are too many mouse 
moved events that are generated by X. Wouldn't it be a better idea
to change the backend to filter out some of those events and not have to have 
this solution reimplemented many times in many places?
There is also a similar and very annoying flood of events when resizing a 
window using an opaque-resizing window manager.

I'm not completely sure, but I think that OS considers the state of modifier 
keys
as they were at the beginning of a mouse tracking session for the whole session,
ignoring changes afterwards.
