Create a ellipsoid centered about the origin. The surface is shaded with the algorithm and surface parameters specified by shaderhandle. xradius, yradius and zradius defines the size of the ellipsoid. resolution is the number of polygons that will be created around it's equator.
Texture is the texture mapping algorithm to use for the object. The NATURAL texture mapping is SPHERICAL. Optional, WORLD is the default.
An object handle that references the new object is returned.
