Send unmap/map events when the view is minimized/restored

X11 Window managers set WM_STATE to notify about minimization, often without
sending core X visibility events (which seems odd to me, but that's what Gnome
does anyway).  So, implement this protocol and send map/unmap events to the
view, and adjust the Windows implementation to do the same for consistency
across all platforms.
