New composite glyphs code uses the updated glamor program infrastructure to create efficient shaders for drawing render text. Glyphs are cached in two atlases (one 8-bit, one 32-bit) in a simple linear fashion. When the atlas fills, it is discarded and a new one constructed. v2: Eric Anholt changed the non-GLSL 130 path to use quads instead of two triangles for a significant performance improvement on hardware with quads. Someone can fix the GLES quads emulation if they want to make it faster there. v3: Eric found more dead code to delete Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net>
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.
