------- Additional Comments from Zan Dobersek <zandobersek at gmail.com>
This is a small hack, adding 20 to the display number when the driver is also
doing the pixel tests. It theoretically works as long as the number of workers
is below 20, so feel free to advise on what to actually do to make this
bullet-proof. The basic idea is for each driver to have its own Xvfb process up
and running. This is the reason of the flakiness that caused bug #72599 to
disable the ref tests.
