[Paraview-developers] Paraview offscreen rendering and graphical unit tests

[Maxim Torgonskiy]

Thanks Shawn,

I've launched 'ctest -R vtkRendering' in my docker image and it works
(99% tests passed, 1 tests failed out of 257). The only failed test is
' 789 - vtkRenderingCoreCxx-TestFollowerPicking (Failed)'.

If someone finds this helpful, I've build it in the docker
debian:stretch with the system llvm-dev, mesa 13.0.3 and paraview
5.3.0 (release from archive). The configuration arguments are the
following:

mesa (identical to wiki):
===================================
  CXXFLAGS="-O2 -g -DDEFAULT_SOFTWARE_DEPTH_BITS=31" \
  CFLAGS="-O2 -g -DDEFAULT_SOFTWARE_DEPTH_BITS=31" \
  --disable-xvmc \
  --disable-glx \
  --disable-dri \
  --with-dri-drivers="" \
  --with-gallium-drivers="swrast" \
  --disable-shared-glapi \
  --disable-egl \
  --with-egl-platforms="" \
  --enable-gallium-osmesa \
  --enable-gallium-llvm=yes \
  --enable-llvm-shared-libs \
  --disable-gles1 \
  --disable-gles2 \
  --prefix=$installdir
===================================

paraview:
