This makes use of the new test infrastructure.

Any Lagrange quads whose corners match will be considered
identical by the geometry filter. This should work in all
but the most degenerate configurations. The test is
significantly more complicated if mid-edge and mid-face
nodes are to be compared.

... which failed when multiple elements were in the same mesh.

Add several methods to the Testing base class that all VTK-Python
unit tests should inherit:

+ `pathToData(filename)`, which returns the full path to an input
  dataset specified on the command line given just the filename
  part as an argument;
+ `pathToValidatedOutput(filename)`, which returns the full path
  to a file containing validated baseline output (such as an
  image) given just the filename part as an argument; and
+ `prepareTestImage(interactor)`, which can be used in place of
  `vtk.test.Testing.compareImage(...)` when no baseline exists
   yet. When invoked, it starts the interactor. When the interactor
   finishes, the camera position and window size are printed as
   a Python script that can be pasted into a test. Some mouse and
   keyboard events are also returned to the program and could be
   used to inject interaction events for testing widgets.

These methods make Python unit tests, especially those involving
image comparison, significantly simpler to write and maintain.

... which will be used by the arbitrary-order Lagrange
polynomial cells being added to vtkCommonDataModel.

Make the dataset surface and unstructured-grid geometry filters
process Lagrange elements properly.
Note that the unstructured-grid geometry filter does not handle
arbitrary-order elements; because it has a hardcoded maximum
number of points for indexing "surfels" (bounding surfaces of
3-d cells), it can handle at most order 4 quadrilaterals.

This also fixes some issues with the hex and quad cells.

The cache variable LastWindowSize was used for checking whether
RenderToImage FBO needs to be updated as well as for checking
whether DepthPass FBO needs to be updated. If both the modes were
used together, the depth pass updates the cache value and never
lets RenderToImage mode update its FBO.

When reading files with Fortran records that have leading and trailing
length fields per record, we can end up with multiple records for the
same if the record length is greater than 2,147,483,639 bytes (See
https://software.intel.com/en-us/node/525311).

This commit refactors the vtkMultiBlockPLOT3DReader and
vtkMPIMultiBlockPLOT3DReader to support records comprising of
sub-records.

Using SystemTools and Directory can be very inefficient
when dealing with a large number of processes. These classes
are esentially wrappers for SystemTools and Directory such
that only process 0 does any file system introspection and
then broadcasts that information out to other processes.
