When a flip (or unflip) is pending and a flip request comes in, leave it queued until the pending flip completes and then execute it. This fixes a bug where an application submitting back-to-back present_pixmap requests for sequential frames would alternate between flipping and copying as the pending flip would cause the new present_pixmap request to not use a flip.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
