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.
