My understanding is that a client can tell the shell that a window can 
be dragged in response to any click, so potentially any point on the 
window can be a drag point.

I think it is a reasonable assumption that the point that caused the 
drag will continue to cause a drag if clicked again. Therefore the 
window will remain movable as long as that point is not obscured.

Therefore I suggest that the sample client work as proposed, and only 
prevent that point from being obscured.

Other shells may decide to be more restrictive (such as insisting that 
the entire input area remain un-obscured) but the sample shell should 
show what is possible and allowed.
