Are you saying that a sub-surface that extends outside the area of the 
parent surface should cause mouse/touch events in this extended area to 
be delivered to the parent?

My personal feeling is that the intuitive approach that events are 
delivered "normally" to subsurfaces is the correct one. Especially if 
subsurfaces are going to be the method of embedding one client inside 
another. I think it is ok to say that subsurfaces with non-empty input 
areas are broken in toytoolkit.
