with C++ counterparts.  Changed only vtk*.cxx files.
Didn’t touch .h or .c or any 3rd party.

Use vtkOpenGL.cmake to decide to use (LINK_PRIVATE) OpenGL or Offscreen Mesa.
OpenGL is now LINK_PRIVATE, so additional libraries and tests need to include OpenGL.
Include the following in your CMakeLists.txt:

include(vtkOpenGL)
vtk_opengl_link(${module})

for every ${module} that uses OpenGL. This takes care of include directories and
linking of proper libraries.

We no longer need this compatibility layer for the compilers we support.
Use the following commands to switch to standard header and namespace:

 git grep -l vtksys/ios/ | xargs sed -i 's|vtksys/ios/||'
 git grep -l vtksys_ios | xargs sed -i 's|vtksys_ios|std|g'

We no longer need this compatibility layer for the compilers we support.
Use the following commands to switch to standard header and namespace:

 git grep -l vtksys/stl/ | xargs sed -i 's|vtksys/stl/||'
 git grep -l vtksys_stl | xargs sed -i 's|vtksys_stl|std|g'

In the early days of VTK, support for stl was not portable. vtksys_stl
and vtksys_ios provided a portable implementation of the stl. Now, all
of the VTK supported compilers have portable stl implementations.

This patch:
  1) Replaces the vtksys_ios:: with std::.
  2) Replaces the vtksys_stl:: with std::.
  3) Removes "using" statements for stl

This is not supported by the new OpenGL2 backend, and doesn't support
new text features, like MathText, FontConfig, or custom font files.

It only implements vtkTextMapper, which now will use a texture-based
implementation, similar to vtkTextActor and friends.

This change makes more modules dynamically switch between the
rendering backends if they have no OpenGL code, or introduces some
ifdefs in the case of RenderingParallel (which may not be functional
at this stage). Added RenderingFreeTypeOpenGL2 which will also need
some additional work before it is properly integrated with the new
rendering backend, but it surprisingly seems to render on the
desktop.

This commit contains everything needed to get a minimal ParaView
build using the new rendering backend for polygonal rendering.

There were a lot of abstract classes defined in Rendering/Core or
Rendering/Volume that the OpenGL2 backend has not implemented yet.
This causes a crach whenever such a class is instantiated as is
done by some of the tests. The fix is to either remove or provide
implementations for these classes. For the volme code this patch adds
a VolumeOpenGL2 directory which will be where the new/converted
volume rendering implementations will go.

The other big piece is the painters. As we are not/can not support that API
the classes were moved to OpenGL. The excpetion is the PainterDeviceAdapter
which is part of RenderWindow. When building with OpenGL2 that class is
treated in RenderWindow as a plain vtkObject that does nothing.

vtkSmartVolumeMapper is not currenty built by OpenGL2 but could be if we
are willing to add a bunch of ifdefs. The basic approach is there already
in the class, just need to add a bunch more if we want to have that in the
short term prior to the new GPU mapper being completed.

This patch includes some other fixes that were required to get the tests to
pass. Generally related to missing file properties or extra includes that
were not needed.

This enables us to compile the Geovis module without depending on
the OpenGL implementation, after discussing it with Aashish this
class may be deprecated and removed in the future.

These can only build with the OpenGL backend.

Refactoring the way VTK goes between piece and structured
extents. Before, extent translators were used when the pipeline
moved from structured to unstructured data converting piece
request to extent request. This caused many problems with filters
that altered extents, mainly a lot of redundant IO due to
repartitioning of different extents. This became extremely
cumbersome to manage when running distributed. The new behavior
pushes the extent translation all to way to the readers and
only when readers are able to read a subset. This works much
better. The only downside is that filters need to be able to
handle data extents different than update extents. Most filters
can do this but many imaging filters cannot. Those that are
needed in parallel will have to be updated.

As part of this work, I also removed MAXIMUM_NUMBER_OF_PIECES
and added CAN_HANDLE_PIECE_REQUEST. MAXIMUM_NUMBER_OF_PIECES had
reduced to being a boolean. 1 for serial sources, -1 for parallel
...

In other words, changed from the C to the C++ header name.
Did this only in .cxx files, and not in ThirdParty.

Baseline images are now referenced by ExternalData content links stored
directly in each module source tree.  Drop the old VTKData baseline
subdirectory name from the vtk_add_test_* signatures.

Tell calls to vtk_add_test_(cxx|python|tcl) explicitly when there is no

When tests are run with -I they must be linked with InteractionStyle.

On the Mac, tests must be linked with MACOSX_BUNDLE to get keyboard
focus.

Use #ifdef instead of just #if to fix some -Wundef warnings.
In most cases, this just makes things more consistent with
existing code.

Some tests that used OpenGL classes did not include OpenGL headers.
This worked by coincidence on systems where gl.h was in system path.
Didn't work on the Mac.

the freetype module which has a concrete implementation for parts of it.

Previous change cause many complication errors because Rendering
no longer automatically brings in IO modules. Manually added IO
dependencies where it makes senses and removed the IO dependency
otherwise.

The StandAlone + Rendering groups should contain what was in VTK
before modularization without turning on additional flags.

The StandAlone group is a special group of all modules that need no
external dependencies, such as Boost, MPI, etc. It does include
modules that rely on third party libraries VTK can build (by
default). It DOES NOT include modules that depend on OpenGL. Those
modules are in the Rendering group.

Several modules that meet the above criteria for membership in the
StandAlone group did not specify their membership via the GROUPS
StandAlone property. Also, several modules were missing from the
Rendering group.

This topic was verified by building the VTK Wiki Examples:
http://www.vtk.org/Wiki/VTK/Examples/Cxx against an installed VTK that
was built with only the StandAlone and Rendering properties enabled.

The FiltersHybrid module needs RenderingCore for vtkCamera. The
GeovisCore module has a hard dependency on RenderingOpenGL for the
vtkOpenGLHardwareSupprt class, and other things, this also means it must
be removed from the StandAlone group due to the GL dependency.

The InteractionWidgets module had a few dependencies that were not
clear, and has an OpenGL dependency for one of the widgets that looks
like it can be factored out.
