• ColorUtils.rgbToHsv() got moved into Color.getHSV()
• Geometry no longer has a materials property. MeshFaceMaterials usage is now like this: new THREE.Mesh( geometry, new THREE.MeshFaceMaterial( [ material1, material2 ] ) ). Meaning that face.materialIndex will map the array passed to MeshFaceMaterials.

• Vector3's .getRotationFromMatrix( matrix, scale ) to Vector3's .setEulerFromRotationMatrix( matrix, order ).
