VTK  9.0.1
Todo List
Member _vtk_module_add_header_tests ()
Move this function out to be VTK-specific, probably into vtkModuleTesting.cmake. Each module would then need to manually call this function. It currently assumes it is in VTK itself.
Member vtk_module_add_python_package (name)

Support a tree of modules with a single call.

Support freezing the Python package. This should create a header and the associated target should provide an interface for including this header. The target should then be exported and the header installed properly.

Class vtkCachingInterpolatedVelocityField
Need to clean up style to match vtk/Kitware standards. Please help.
Class vtkParallelRenderManager

Synchronization/barrier primitives.

Query ranges of scalar values of objects in addition to the boundary in three-space

Class vtkPolyPlane
Generalize to extrusions along arbitrary directions.
Member vtkTemporalStreamTracer::SetTimeStepResolution (double)
, put back time scaling
