examples/cogl-x11-tfp.c: Wait for the window to be mapped
Wait for the main window (and hence the window we create within
the main window to redirect) to be mapped and become viewable
before we try to call XCompositeNameWindowPixmap() -
XComposeNameWindowPixmap() produces a BadMatch error on a
non-viewable window.
