Summary0005111: coordinate conversions inconsistent
DescriptionThere are myriad ways to convert point locations between DISPLAY, VIEWPORT, VIEW, and WORLD coordinates. For example: vtkRenderer provides SetWorldPoint(), WorldToDisplay(), and GetDisplayPoint() which can be strung together to transform world coordinates to display coordinates; on the other hand vtkCoordinate provides SetCoordinateSystemToWorld(), SetValue() and GetComputedDoubleDisplayValue() which should do the same transformation.

However, the two methods don't always agree.

There are more examples of conversion inconsistency between vtkRenderer and vtkCoordinate, as demonstrated by the attached test case.

 Note: the file coordinateConversion.cxx is meant to drop into directory Rendering/Testing/Cxx, and be added to the tests:

 Note that the bug persists in VTK 5.6 I've uploaded a shorter file (testCoordinateConversion.cc) that demonstrates it.
