I see that Flam_Bayer.inc is not in 3D. That's used in java script, which can
generate a library view in a split sec, it doesn't have to use trig.
Could be quickly rewritten to any format you want.

ra dec is simple, just get the right order.
#local v = <cos(radians(ra))*cos(radians(dec)),
sin(radians(dec)),
sin(radians(ra))*cos(radians(dec))>;

dec * -1

if you want to y+ down output
