Summary0012842: segfault in vtkVolumeRayCastSpaceLeapingImageFilter
DescriptionHi,

In 3.12 when volume rendering on image data I'm experiencing segfaults in vtkVolumeRayCastSpaceLeapingImageFilter in vtkVolumeRayCastSpaceLeapingImageFilterMinMaxExecute. The issue seems to be that vtkImageData::ComputeIncrements relies on active scalars being set. However, for use with ParaView I don't think this can be guaranteed. for instance how would an object that produces multiple arrays, eg a reader, correctly set active scalars?

A quick fix is below, the real fix probably is quite a bit more involved.

   const unsigned int nComponents = (this->GetIndependentComponents()) ? components : 1;
