[vtkusers] VTK 7.1 error "Shader failed to compile" with GPU Volume rendering and clipping planes

[Simon ESNEAULT]

Hello,

I've found the error, it is located in vtkVolumeShaderComposer.h, if
someone use GPU volume rendering, cropping and clipping at the same time,
the variable vec4 temp gets declared twice.
Renaming 'temp' to 'temp_clip' fix the crash.

HTH someone ;)
