FOVMagnitudeLimits effectively sets the four magnitude slider widgets  
for the FoV to whatever you set them to.

FOVStarLimits is probably not really of much use in V2, since the  
rendering of stars is somewhat cleverer than in V1. Actually, I'm not  
even sure it's necessary in V1 most of the time, and remains there  
mainly for legacy reasons. I would avoid using it. At a later stage I  
will investigate further and see if it needs to be deprecated.
