Subject: [PATCH] gtk3: stop the ever shrinking size of toplevel on every
 restore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

for getting and setting the window state, work on the toplevel m_pWindow. Leave
the "geometry" alone as its for the purpose of the current known size of the
toplevel window contents
