single texture skybox bug fix
removed unused import
Reintroducing RotateAroundAnimation3D. Back by popular demand because of its simplicity of use.
Added a new class that performs Spherical Linear Interpolation (SLERP) between to Vector3s.
Updated the OBJ exporter to reduce memory consumption. Data is now written with a buffered writer and data is written proximately every 8192 characters. This should greatly reduce memory consumption for the cost of slightly increased CPU load.
