Why not allow 3 SH Bands?

[GroCodeJack]

I see that the viewer only allows 0, 1, or 2 sh level, but my splat looks best with 3. Why are 3 SH bands not possible?

Mainly for simplicity's sake :) The code to render the third band will be the most complex out of all of them. I do tentatively plan on adding the third SH band at some point.... I just need to find the time.
