- support for quaternions, euler, vector, matrix operations. - euler supports unique rotation calculation - new matrix memory construction and internal functions - quaternion slerp and diff calculation - 2d, 3d, 4d vector construction and handling - full conversion support between types - update to object/window to reflect to matrix type - update to types/blender/module to reflect new module
