Trying out the mapping warp on the texture to get a feel for the method, 
but not sure how to make the image occupy a different sector of the 
sphere... warp{spherical orientation z dist_exp 1} scale <-0.5,0.5,0.5> 
rotate 90*x gives a segment from 90 degrees 'south' to the 'equator', 
and 0 to 180 degrees 'west'...changing the rotation only changes the 
position of that wedge, and I want to have the image occupy, for 
instance, 0 degrees to 45 degrees north and 90 degrees to 135 degrees 
west.  The documentation doesn't seem to elaborate on this aspect.
