Søren Sandmann Pedersen 9cbcb5bd6a Use new pixman_glyph_cache_t API that will be in pixman 0.28.0 
This new API allows glyphs to be cached in a data structure in pixman,
and entire glyph strings to be composited in one go.

Also bump pixman dependency to 0.27.2.

					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.

For a comprehensive overview of X Server and X Window System, consult the
following article:

All questions regarding this software should be directed at the
Xorg mailing list:
