osx/stage: Synthesize an enter event on show

Browse Source 
If the pointer is inside the window frame when it's shown then we need
to synthesize and emit a NSMouseEnterEvent ourselves, as Quartz won't
do it for us.

This is a bit of a blind commit - but it's taken from an equivalent
patch that has been verified to work in GDK.
