Impressive patch. It will certainly be fun to test this. 

It has quite a bit of overhead though, since you store the pointer window
per-widget. Since your patch seems to satisfy the following conditions:

1) at most one widget at a time can have the HAS_POINTER flag set

2) you only ever look at the pointer window of a widget if it has HAS_POINTER
set

it should be possible to take Owens approach of storing a global pointer window
per display instead. Right ?

One detail I wonder about is if it can happen in
_gtk_widget_synthesize_crossing
that from != to but from_window == to_window (thinking of no-window widgets
sharing the window with their parent), in which case

+  else if (from_window == to_window)
+    ;

may cause missed events. But maybe that case can never happen...
