Subject: [PATCH] Fix wxTopLevelWindowGTK::DoSetSizeHints if a window scale
factor larger than 1  is set.

In this case, passing INT_MAX as maximum width/height hint
to gtk_window_set_geometry_hints leads to integer overlows.

Instead, use INT_MAX / 16 which should work with all
resonable scale factors.
