--Bug fixes

Browse Source 
-Fix variations: blob2 (broken on CPU), epispiral, hole.
 -Fix reading variations from Apophysis: supershape.
 -Bump render was broken.

--Code changes
 -Flip precalc sina/cosa and apply everywhere by flipping the usage. Flam3 had these reversed and it made the code confusing to read.
