Description

Difference is observed between FormFactorFullSphere(radius) and FormFactorTruncatedSphere(radius, radius*2.0),
i.e. when truncated sphere just mimics a full sphere.
The difference exists in layer with absorption (imaginary part of refractive index is not zero). In layers without absorption results coincide.

Use FunctionalTests/TestPyCore/transform_truncatedSphereComposition.py as an example.
Test fails (python transform_truncatedSphereComposition.py) as it is now. If you remove absorption from the material of the middle layer by editing line 25 (teflon material) - the test will pass.

In the attachment I put the plot with difference map.

Since it one of the most used shape, I put priority to high.
