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.

We have machines with 24 cores.  Instead of adding a constant, we could have:
display_id = (self._worker_number + 1) * 2
if self._pixel_tests:
    display_id += 1

Thanks for the review! Rather used 'self._worker_number * 2 + 1', just to number the displays from 1 onwards.
