Disabling translation and scaling now works.

These flags were ignored in the code. They have been inserted into the
event handling logic.

Added the ability to specify a clip tolerance.

The clip tolerance can be set now. Default is FLT_EPSILON. Setting to too
large a value will cause numerical problems.

Fixed bug causing plane to disappear on boundary.

When the plane was moved to one of the sides of the bounding region, and
was parallel to the bounding region, it sometimes disappeared. To fix this
the origin of the plane is clamped to slightly within the bounding region.

InsertNextCell and related method now return the proper vtkIdType.

Some of the methods in vtkPolyData and vtkCellTypes were returning int
when they should have used vtkIdType.

Create vtkPolyData instead of vtkUnstructuredGrid when passing points.

This is a feature / performance request.

bug #14418: Remove addition of "-Wno-deprecated" compiler flag

The suppression seems no longer necessary, at least
in all the configs I've tried, which includes old PPC OS X 10.5
and Intel OS X 10.8, with gcc and clang.

Remove accidentally added test data files

In commit 352e3122 (Add test for vtkOpenFOAMReader, 2013-12-24) we
accidentally added files prefixed in "._" in addition to the actual data
files.  These files aren't real and, when you archive and untar a vtk
release, produce file exists warnings.

Removed priority based streaming and fast path.

Removed priority based streaming and fast path codes in
preparation for future refactoring. These were polluting core
classes despite having a small user base. In the future, they
may be refactored into the appropriate subclasses and "plugins".

Fixed the BiQuadraticQuad interpolator

The original ordering switched x-coords with y-coords, generating
incorrect coordinates for the interpolated point.

Change-Id: I84fa6b399746523c5a7478f693e08e3253a55b48
Added a test for biquadratic quad interpolation

This is based on the code in https://github.com/Kitware/VTK/pull/5
submitted by Antonio Cervone.
