Refactored the getOrigin helper to help fix the relative affine animations

This commit refactors the getOrigin helper, in order to send the origin to the correct
space. The origin should be expressed in the space of the last animation.

Changes
=======
- Refactored the getOrigin helper
- Added a simple example to the dirty file to test multiple transformations
