Quaternions - solid on orbit trapping

[David Makin]

Hi, I finally got around to trying the new algorithm that "fixed" the delta DE method out on a DE style method for solid on orbit trapping, 1st results:

Note that the render time was just under 1 minute per frame @640*480 which I'm rather pleased with given the difficulty of getting the thin bits rendered accurately. The max iterations used for the above animation was just 8 and "solid" is based solely on the point trap distances.
