Thanks! I'm working on doing the same with an ellipsoid, but have run 
into some problems:

1. How do I map the texture to the ellipsoid? Do I apply the texture 
before shrinking the sphere or after? (I *think* I should do the latter.)
2. Should I use geodetic latitude, geocentric latitude or reduced 
latitude? (In this case I *think* the first one is the one to use.)
