In __glXScreenInit() we generate the set of GLX visuals in two steps: first we match each pre-existing X visual with a corresponding FBConfig, then we generate a new X visual to correspond to all the remaining FBConfigs. The first step is used for the two default 24-bit visuals (true color and direct color) and for the 32-bit visual. If windowsystem multisampling is enabled in Mesa, we need to ensure that none of these three visuals gets matched to a multisampled config. Fixes a bug with windowsystem multisampling in gnome-shell. If the X server happens to match up a multisampled FBConfig to the 32-bit visual, gnome-shell will try to use it to read pixels from alpha-blended windows (such as gnome-terminal), resulting in no window appearing on screen.

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.
