Summary0010018: vtkProcrustesAlignmentFilter fails to align shapes in similarity mode
DescriptionThe attached program demonstrates a problem where the vtkProcrustesAlignmentFilter fails to align shapes correctly (the scaling and
translation works but rotation fails) when using the similarity transformation mode. The problem can seen when running the attached program without passing any arguments.

The problematic shapes are triangles where one end is "cut", i.e. the end vertex replaced by two vertices on the sides close to the end.

The program also demonstrates how the problem disappears if the shapes are ordinary triangles (run the program with argument 't')

The problem seems to also disappear if the triangle vertex arrays are re-ordered so that the "cut end" is at the same array indexes for all shapes.
This can be seen when the program is run by passing any argument != 't'.

Just found out the Procrustes requires one-to-one landmark correspondence in shapes, therefore the behaviour demonstrated by the program seems to be correct.

Please remove this problem as no-problem.
