Thomas Hellstrom 91c42093b2 glx: Duplicate relevant fbconfigs for compositing visuals 
Previously, before GLX_OML_swap_method was fixed, both the X server and
client ignored the swapMethod fbconfig value, which meant that, if the dri
driver thought it exposed more than one swapMethod, it actually just
exported a duplicated set of fbconfigs. When fixing GLX_OML_swap_method
and restricting the choice for built-in visuals to a single swap method
that meant we didn't have that many fbconfigs to choose from when pairing
the compositing visual with an fbconfig, resulting in the fbconfig paired
with the compositing visual becoming too restrictive for some applications,
(at least for kwin). This problem would also happen if the dri driver
only exposed a single swap method to begin with.

So, to make sure the compositing visual gets a good enough fbconfig,
duplicate fbconfigs that are suitable for compositing visuals and make
sure these duplicated fbconfigs can be used only by compositing visuals.
For duplicated fbconfigs not paired with a compositing visual, construct
new compositing visuals, making compositing clients able to choose visuals
/ fbconfig more adapted to their needs.

This is in some sense equivalent to adding a new "TRUECOLOR_COMPOSITING"
GLX visualtype.

                      swap method")

					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:
