The tests

    vtkGeovisCoreCxx-TestCoincidentGeoGraphRepresentation2D
    vtkGeovisCoreCxx-TestLabeledGeoView2D

fail with PROJ 4.9.3 and above due to a change in the projection
used.  This PROJ version is now what we bundle with VTK.

Since these tests cover deprecated code anyway, simply remove them.

Although hosted at `proj4.org`, the library is called `PROJ` and has
now released version 5.  Drop the version number from our module name.

Populate a script with `map_<md5>=<sha512>` variable settings and
then run the following to convert the content link files:

    git ls-files -- '*.md5' | while read f; do
      md5="$(cat "$f")"
      sha512="$(eval echo \${map_$md5})"
      rm "$f"
      echo $sha512 > ${f%.md5}.sha512
    done

The GDAL raster reader creates cell data instead of point data.

warn_unused_result and not all enumeration cases handled for switch

A special place for GDAL based image projection filters

This required some clean up, because the automatic changes borked a couple of files, but mostly resulted in stupid whitespacing. A few find/replace fixed things up.

There are now some duplicate semis because it did changes like:

  ~AMRIndexIterator() override{};
to
  ~AMRIndexIterator() override= default;;

Note there was a pointless semi before, which clang-tidy didn’t expect / account for.

My next commit will remove them.

The old MapDataArrayTGoMultiTexture relied on
being able to lock dowwn a specific texture unit
which cannot be guaranteed as external code
or render passes may bne uising that texture unit.

Instead we support the method having the name of a texture
along with the matching ethod in vtkProperty to name
a texture. Between these two users can assign texture
coordinate arrays to specific textures.

Deprecated the old index and unit based methods.
Removed a no longer needed vtkTexture.h include
which may bite some folks who are using vtkTexture
but not including the header (which they shoudl do)

Found with regexes:

Mostly removing superflous double whitespace on both user-facing and non-user-facing strings. Some misc. typo fixes sprinkled in as well.

This topic changes the shadow map passes in VTK to use an exponential
function which behaves a bit better and is faster.

also fix a bug where for directional lights the parallel
scale was double what it should be.

Also add in the capability to support subsurface scattering
by compouting a thickness value in the lighting calc.

Now that instantiators are gone, nothing cares about the ABSTRACT
property.

Typos fixes for documentation and source code comments. This commit is a follow up to:   vtk/vtk!3424

Now that VTK requires a C++11 compiler we can ditch using custom typedefs to
wrap =delete;

Now that VTK requires a C++11 compiler we can ditch using custom typedefs

Adding in functionality to allow inserting vtkNew objects into
stl containers of vtkSmartPointer objects as well as comparisons
between vtkNew objects and raw pointers. Also removing Get() and
GetPointer() calls from vtkNew objects since in most instances we
can just pass in the vtkNew<> object instead of having to use the
Get() or GetPointer() methods to get the raw pointer.

examination indicates it should be rmeoved

This topic is the result of running clang-tidy to
modernize our usage of NULL and 0 to nullptr. It also
includes some manual and semi manual changes where
clang-tidy would not be expected to work (such as in
comments, or classes not compiled on this build)

There are definitely many comments and occurances that
this topic misses that we will need to fix over time.

Found & auto-fixed by clang-tidy’s readability-container-size-empty check.

empty() is guaranteed O(1) while size() is not, thus could be faster in some cases.

snprintf is now part of C++11 and is already simulated for old versions of VS.

doxy and misc. typos pt2

- Made a few APIs' params const
- Changed many usages of the evil GetBounds() to expect a const
  return value, even though it does not (yet?) return const
- Slightly changed return values of vtkTextActor3D::GetBounds()
  to return its own ivar instead of its ImageActor's

This fixes performance warnings for cppcheck.

These are small differences in label size and location.
