Chun-wei Fan 45b19724c8 GDK/Win32: Drop AeroSnap emulation 
It turns out that this AeroSnap emulation can really get in the way
as we try to modernize and clean up the codebase, so drop the support,
and so clean up the GDK/Win32 code a bit as a result.

We really want to clean up the event handling and resizing handling a
bit here.
