I didn't do this on purpose, it just worked out this way. In a way, I haven't
really designed the 3DLDF language myself, it's based on Knuth's Metafont
language. There are differences because of the differences between 2D and 3D
and because font design doesn't require the same kinds of basic geometric
types that 3D graphics does. Nor has it been possible for me to implement
certain things in Bison that Knuth does with his hand-written parser code,
although I don't claim that it's impossible in principle. I'm also not as
clever as Knuth.
