If a pixmap is not exportable, `glamor_gbm_bo_from_pixmap()` would fail
and the modesettings driver would consequently fail to do its page flip,
which both prevents Present from working and also fill up the logs with
error messages such as:
(EE) modeset(0): Failed to get GBM bo for flip to new front.
(EE) modeset(0): present flip failed
Refactor the code so that `glamor_gbm_bo_from_pixmap()` takes care of
making the pixmap exportable.

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.
