Here's some mesh making macros I'd like to have some feedback on. Don't 
rely too much on them as they are still changing and some depend on the 
buggy POV-Ray 3.5 splines that also may change.

*Changed parametric a bit, for the better / for the worse?

*Add, where possible, endcapping options?

*Make the macros that use splines more general so they can take arrays 
with points as input. Then provide macros that turn splines, functions 
etc. into point arrays?

*Switches to turn off/on normals, uv_coordinates? Switch to generate 
uv_coordinates in the BuildWriteMesh2 macro instead of on the fly like 
in parametric? The uv-range then would always go from <0,0> - <1,1>.

*Other?


There are three more macros under construction:
* Ruled surfaces, kind off, uses more than 2 splines and does not 
do only linear interpolation. It's finished but very mutch bitten by 
the spline bugs, so I'm not shure wether it actually works right.
* Prism2, works like Double Sweep in Amapi3D. Half way there.
* Gordon Surface, probably too ambitious. Should be like Coons though, 
but with more splines (adding 'extended' ruled surfaces?).
