- Fixed some minor bugs.
- Added a new feature called 'MapOnScalarClipWithRotation' that clips a two-dimensional data with a scalar value and subsequently rotating it to create a three-dimensional effect.
- Corresponding examples, test cases and documentation of the new module have also been added.
