Clutter still uses part of the deprecated stateful API of Cogl (in particulart cogl_set_framebuffer). It means Cogl can keep an internal reference to the onscreen object we rendered to. In the case of foreign window, we want to avoid this, as we don't know what's going to happen to that window. This change sets the current Cogl framebuffer to a dummy 1x1 framebuffer if the current Cogl framebuffer is the one we're unrealizing. https://bugzilla.gnome.org/show_bug.cgi?id=754890
