Shared pixmap destruction is done by unrefing the master pixmap twice: once for the original reference, and once for the reference implicitly added by PixmapShareToSlave. Then, unrefing the slave pixmap once. When I add PRIME double buffering and synchronization, I will need to do this in multiple places. To avoid duplication of code and comments explaining it everywhere, factor it out into its own function and use that in place of where it was before.

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.
