My Vote would be to feel free to exclude them. What often happens is that
the extension manager checks for the required extension and the driver
claims to properly support the functionality but in fact the driver doesn't
correctly implement the feature/we're using it incorrectly/or the driver is
flat out lying and doesn't support the feature at all. This makes
implementing a graceful way to detect lack of support for these gl
extensions very tricky.

Hi all,<br>
<br>
For years now, there are VTK tests that fail on some GPUs.  Previously,<br>
on our dashboard machines, we added them to the exclude list.  Rogue3 uses:<br>
<br>
&quot;^TestGenericVertexAttributesGLSL|^TestBlurAndSobelPasses|<br>
^TestGaussianBlurPass|^TestShadowMapPass|^TestSobelGradientMagnitudePass|<br>
^TestTStripsColorsTCoords|^TestTStripsNormalsColorsTCoords&quot;<br>
<br>
I was going to add to that TestProjectedHexahedra and<br>
TestSmartVolumeMapperWindowLevel because they always fail too:<br>
&lt;<a href="http://www.cdash.org/CDash/viewTest.php?onlyfailed&amp;buildid=827790" \
target="_blank">http://www.cdash.org/CDash/viewTest.php?onlyfailed&amp;buildid=827790</a>&gt;<br>
 <br>
François was going to add some code so that tests could &#39;fail<br>
gracefully&#39; if the GPU did not have the necessary features.  That would<br>
be really nice, is it on anyone&#39;s radar?  Should I exclude these test<br>
anyway in the meantime?<br>
<br>
Thanks,<br>
<br>
