Important points
----------------

- In Lottie, all the parts of shapes/elements lying outside a precomposition are cut off and never displayed. Hence the over all size of a pre-comp is increased by some amount as a precaution. Some part which is outside a pre-comp might come inside the overall canvas after some transformations(rotation/translation/scale). This increase is given by:
  ``ADDITIONAL_PRECOMP_WIDTH`` and ``ADDITIONAL_PRECOMP_HEIGHT``
