force a software render in all cases when finalizing x11 client iconify 

since ICCCM requires that clients be unmapped while iconified, it's necessary
for the compositor to perform one last render prior to the unmap in order to
ensure that mirror objects will still appear as expected. this render must use
the pixmap buffer data in order to avoid timing issues due to async/deferred
rendering, and it is only necessary for the case of clients rendering with a
native surface
