Started out as an Xorg module to be used from Xorg drivers to let Xorg run under a wayland server. The idea was to be able to reuse the 2D acceleration from the Xorg driver. Now with glamor being credible, a better plan is to just make Xwayland its own DDX, similar to Xwin and Xquartz. This is a much better fit, as much of the code in the original approach had to hack around Xorg doing Xorg things like take over the VT, probe input devices and read config files. Another big win is that Xwayland dosn't need to be setuid root. The Xwayland support for DRI3, Glamor and render nodes was done by Axel Davy <axel.davy@ens.fr>, who also did a lot of work on the rebase to the Xwayland DDX.
