[I did a half-mapping of each half-sphere, top and bottom -- was able to use the same image in either case, didn't have to slice or dice that at all]

The current implementation in LDCad uses a hack to make full sphere mapping possible as the literal spec will cause problems past 180 degree. So I'm using longitude / latitude mapping to generate the texture coordinates to get around that. It's an optional (currently enabled) feature though as I wasn't sure the spec was intended to support >180 deg (by limiting this on the authoring side.)

Also there will still be problems at the poles when using certain orientations of the texture (resulting from misalignment of vertices).
