Keyword substitution: kv
Default branch: MAIN

ENH: Deprecated vtkTemplateMacroN(). vtkTemplateMacro() should be used instead

ENH: Change vtkImageData::Increments from int to vtkIdType to allow processing of large images

ENH: removed GetPipelineBlah methods

BUG: Fix support for VTK_FLOAT

ENH: Bring Graphics and Hybrid up to date with the trunk

ENH: Port cleanup from CVS

ENH: Cleaning up the code. replace individual switch statements with template macro

ENH: make the new pipeline the default

some cleanup and changes

ERR: missed a break; statement

ERR: When VTK switch to double occurred, FLOAT was outlawed as a grid datatype.
This change brings float back.

ENH: update Floor and Round to match vtkImageReslice

ENH: Some more float to double update

ENH: Added fast floor code from vtkImageReslice

remaining next double changes

ENH:Copyright changes. Hopefully the last time ever.

ENH: the call to GetIncrements() was keeping the code from scaling on the
SGI Altix system we're trying out, because every time it is called it
writes into the Increments ivar.  Writing to that ivar is very expensive
for the CPUs that don't own that ivar's memory!

ENH: Implementation 2 of ios wrapper.

ENH: Renamed vtk_ostream to vtkOStream, vtk_istream to vtkIStream, and vtk_ostrstream to vtkOStrStream.

ENH: Using iostream wrapper classes to speed up compilation.

removed statics

FIX: Remove dependency on vtkImageData in header file

ENH:Updated copyright: new year and streamlined

ENH: Three sweeping changes.

1.) vtkTypeRevisionMacro is now used in all VTK classes in place of
    vtkTypeMacro.  It invokes the original vtkTypeMacro and then adds
    a protected CollectRevisions method for future use in serialization.
    A corresponding vtkCxxRevisionMacro has been added to every .cxx file
    to implement the CollectRevisions method for each class.  This will
    allow collection of every class revision at run time.  Any new VTK class
    should use vtkTypeRevisionMacro instead of vtkTypeMacro.  The .cxx
    implementation should then have the following line:
      vtkCxxRevisionMacro(vtkFoo, "$Revision: 1.1 $");
    CVS should insert the correct revision number when the class is commited.

2.) vtkTypeMacro now also adds a typedef called "Superclass" to refer to
    the superclass of any VTK class.  All PrintSelf methods have been
    updated to call their superclass's PrintSelf like this:
      this->Superclass::PrintSelf(os,indent);
    This should reduce the number of places that refer to a superclass
    by its actual name.

3.) The standard ::New() method implementation has been replaced with a
    macro.  Instead of an explicitly written implementation to try the
    object factory and then call the new operator, VTK classes should
    instead use the following macro unless they have a special New() method:
      vtkStandardNewMacro(vtkFoo);
    This will implement the New() method in the standard way.  The line
    should appear in the .cxx implementation file, not in the header.
    Using the macro will make it easier to change the standard
    implementation of the method.

Also removed tabs from many files.

ERR: undefimed memory copy detected by purify.

Additional tuning of the inverse warp transformation code

ENH: better criterion for inverse transformation: Newton's method iterates
     until the error is less than the tolerance in both coordinate systems
     (previously, only the error in the source coordinate system was checked)
ENH: ensure that every iteration results in a reduction of the error
     (continue reducing Newton step until this is true)
ENH: clean up the code, adjust so that 'i' counts function evaluations
     rather than Newton steps

ERR: the coordinates printed in the error message when an inverse
     transformation refused to converge were incorrect

:ENH:Copyright update

ERR: style.

New method: InverseTransformDerivative (eliminates one forward transformation
            step when doing the inverse transformation)
ERR: the inverse derivative was being computed at the wrong point in
     the grid transform

ERR: linear interpolation derivatives, subscript typo
ENH: improve efficiency of linear interpolation

ERR: inverse transformation of double points was not working (silly typo)

remove warnings

Documentation enhancements.
Rename some of the vtk*Transform classes, to increase clarity.
new name                   old name
vtkAbstractTransform    <- vtkGeneralTransform
vtkHomogenousTransform  <- vtkPerspectiveTransform
vtkGeneralTransform     <- vtkGeneralTransformConcatenation
vtkPerspectiveTransform <- vtkProjectionTransform
vtkMatrixToHomogenousTransform  <-  vtkMatrixToPerspectiveTransform

ERR: array bounds in cubic interpolation

ENH; The ThinPlateSpline transform is much more robust.  The matrix inversion
     step checks for singular values, so the landmarks can all lie in the
     same plane.  Appropriate action is taken if less than 3 landmarks are
     provided.  The transform inversion is more robust than before.
NEW: vtkGridTransform, a very computationally efficient class for performing
     a warp transformation.
NEW: vtkTransformToGrid, to convert any transform into a grid transform.
