[vtkusers] Fix to vtkVolumeTextureMapper3D progress events

[Matt Hilleman]

This is for VTK 5.0 and the CVS version

Uncomment all the code, in vtkVolumeTextureMapper3D.cxx, referring to:

VolumeMapperComputeGradientsStartEvent
VolumeMapperComputeGradientsProgressEvent
VolumeMapperComputeGradientsEndEvent

Around line 633 change it to the following:

if ( z%8 == 7 )
{
  double args[1];
  args[0] = 
    static_cast<double>(z - z_start) / 
    static_cast<double>(z_limit - z_start - 1);
  me->InvokeEvent(
vtkCommand::VolumeMapperComputeGradientsProgressEvent, args );
}

	Have fun, Matt
