Work around COGL bug causing flash for new windows

COGL bug http://bugzilla.openedhand.com/show_bug.cgi?id=2110 results
in pending drawing at the time of cogl_offscreen_new_to_texture() going
to the newly created framebuffer rather than the stage.

This would result in most windows being missing for the first frame
when a new window is mapped.

Work around this by calling cogl_flush() before
cogl_offscreen_new_to_texture().
