Instead of spheres, the planets are now created as triaxial ellipsoids according to the corresponding radii values in the SPICE kernels (if such values are available). Apart from being more scientifically accurate, the planets are shaped as the intersection functions in SPICE expects. The textures will now also be aligned in longitude as in reality (w.r.t. UTC) when using a texture map ranging from -180 in the left end to +180 on the right, with 0 longitude in the middle (such as Greenwich in Earth texture)
