GL_RED is supported by core profiles while GL_ALPHA is not; use GL_RED
for one channel objects (depth 1 to 8), and then swizzle them into the
alpha channel when used as a mask.
[airlied: updated to master, add swizzle to composited glyphs and xv paths]
v2: consolidate setting swizzle into the texture creation code, it
should work fine there. Handle swizzle when setting color as well.
v3: Fix drawing to a8 with Render (changes by anholt, reviewed by airlied).

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.
