So basically you can trace single windows events and send the update
instead of enumerating all windows in the system every time, right?
Potentially the old way could be used to send not rectangular windows
splitting the windows in different rectangles while with this change
is harder to achieve this.

This changes also mode_list message. Not a big deal as 01/12 is not
merged too. But how is the id used in mode_list?
I suppose id is xid on Xwindows and the handle in Windows.
