That's exactly why I did concede that - quote - "a proper way to /get/ 
font metrics is a prerequisite to implement macros providing 
higher-level text layout capability."

And it's also a great example of why the actual layout functionality 
doesn't belong inside POV-Ray: Hey, I'm a 3D enthusiast, not a font 
expert. All I know is that font-size-adjust uniformly scales the font, 
so to me it's essentially a scaling operation, and I don't bother where 
the factor comes from.

Leave 3D magic to the 3D geeks & POV-Ray developers, and font magic to 
the font geeks & SDL macro programmers.
