+- Added encapsulate and encapsulateBoundingInfo methods to BoundingInfo. ([Tolo789](https://github.com/Tolo789))
 
 ### Engine
 - Moved all instance data from Geometry to Mesh such that the same Geometry objects can be used by many meshes with instancing. Reduces memory consumption on CPU/GPU. ([breakin](https://github.com/breakin)
