<br>
The call to renWin->SetMultiSamples(0) turns off antialiasing. When<br>
GPUs started doing antialiasing by default (not all do, but several do),<br>
people started adding SetMultiSamples(0) to make sure that the same<br>
image is generated by all GPUs.<br>
<br>
Many of the tests in Graphics/Rendering have SetMultiSamples(0)<br>
for this reason.<br>
