Subject: [PATCH] winex11.drv: Leave fullscreen state alone when minimizing.

Currently, when we minimize a fullscreen window, we send the WM an iconify
request followed by an unfullscreen request. Sometimes, window managers
process the unfullscreen request first, causing a reconfigure that we didn't
want.

Firefox for Linux leaves the fullscreen state set while minimized, so WM's
should generally be able to cope with this.
