commit 1a87463083fa9e343aa38b4c8824db0c92645b8e

    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
    
    fix T2788
