I'm trying to add G to POV-Ray, specifically I'm trying to make G 
functions callable through the POV function mechanism. However, the 
number of parameters (and return type) isn't known until a function is 
linked to a G function, and the code seems to take this from the trap 
table where it is defined at compile time. What's the best way to do 
this?

I could add multiple entries in POVFPU_TrapSTable for different numbers 
of parameters. That'd limit the number of parameters, and mean lots of 
entries for one function (16 entries for a max of 15 parameters). I 
can't just modify it at run time, different G functions will use the 
same trap entry. I'm a bit reluctant to modify more than necessary just 
to add my code.
