Added SamplingRate parameter. Now this filter can run faster, by initially sampling the colors at a coarser level. For a sampling rate of (5,5,1), i.e. 25 fewer voxels to build the octree, I got an overall factor of 10-15 speed-up.

Added SortIndexByLuminance parameter. The "index-image" viewed as a greyscale image, is usually quite arbitrary, accentuating contrast where none can be perceived in the original color image. To make the index image more meaningful (e.g. for image segmentation operating on scalar images), we sort the mean colors by luminance and re-map the indices accordingly. This option does not introduce any computational complexity and has no impact on actual colors in the lookup table (only their order).

The object factory overrides vtkNrrdReader to vtkPNrrdReader when an MPI
build is enabled. Since, the test is not added as a parallel test,
it is run with `vtkpython` instead of `pvtkpython` resulting in an
error.

This change disables the object factory override for vtkNrrdReader.

Documentation comments in the example test as well.
Minor code cleanups.

The range is pre-encoded within the 2D transfer functions before they
are made available to the volume mapper

Remove commented code

This fixes the two warnings generated prior on Windows dashboards -
one for "incorrect dll linkage" and the other for "locally defined
symbol imported in function".

This allows the generated header to be added to executables.

This change introduces a new variable called TFRangeType for each of the
three transfer functions of the volume mapper. When set to SCALAR, the
existing functionality of the mapper is preserved, where the function is
scaled over the scalar range. When set to NATIVE, the mapper scales the
function over the range set on the transfer function i.e. min and max of
all the function points. Any scalar values outside this range would be
truncated to the min and max of native range.

This can be used for doing custom shader computations

First attempt at depth based color coding shader
Fix the shader test to keep background black

The user can either replace the whole shader or parts of it.

This change makes the volume mapper use the vtkShaderProgram and
vtkShader API to help with shader management and source string
substitutions.
Split up BuildShader() code into multiple sub-functions for better
readability.

Convenience method that does source substitutions in-place.

This will allow it to be used by other vtkShader consumers like volume
mapper

On Windows, the vtksys::SystemTools::Fopen() function uses the cmake
KWSYS_ENCODING_DEFAULT_CODEPAGE setting for the encoding of filenames.
After this change, people can build VTK libraries that use utf8
filenames by setting KWSYS_ENCODING_DEFAULT_CODEPAGE=CP_UTF8.
