Fixed, thanks.

Fixed, thanks. This was a major problem which has been bothering me for ages;
I finally tracked it down to the fact that the ComputeTextureColour() was
ignoring the absense of a multi-texture flag and potentially performing a
full-depth (up to max_trace_level) trace for each texture it found. In the
case of the blobs in glassthing.pov the sub-components of the blob caused
these extra rays to be cast. It would have affected CSG and meshes too.

I'll probably release a beta.4 soon with this fix.
