I guess it doesn't have to be related to the shadow, just the mouse 
cursor getting close to the edge of the active window. This is how MacOS 
appears to do it. It has shadows but there doesn't seem to be any 
correlation with resizing, it seems to just switch to resizing when the 
cursor is within X pixels from the edges.
