Introduced two function glamor_get_sub_pixmap/glamor_put_sub_pixmap, can easily used to get and put sub region of a big textured pixmap. And it can use pbo if possible. To support download a big textured pixmap's sub region to another pixmap's pbo, we introduce a new type of pixmap GLAMOR_MEMORY_MAP. This type of pixmap has a valid devPrivate.ptr pointer, and that pointer points to a pbo mapped address. Now, we are ready to refine those glamor_prepare_access/glamor_finish_access pairs.

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.
