[patch] unmap GtkWindow child when iconified

[Alexey Spiridonov <lesha netman ru>]

Hello,

I'm wondering why GtkWindow doesn't unmap its child when it gets unmapped
during iconification. The benefits are clear -- this would make sure that no
cycles are wasted drawing updates that are unnecessary. Here is an attempt
at a patch, adding a few lines to gtk_window_event. Can someone comment
please? 

Thanks,

Alexey
