Formulas using fn1(x*x)

[LegalizeAdulthood]

In the formula parser, using fn1(xx) and setting the function to ident gives different results on the dos fractint compared to beta 5. It is as if the parser is treating the parameter as just x, not xx.

This can be demonstrated here:

These two formulas should render identically, but they don't.

simon0063-A {
  ; Trying to figure out ident
  ;
  z = p = pixel:
  z = fn1(z * z) + p
  |z| < 4
}

simon0063-B {
  ; Trying to figure out ident
  ;
  z = p = pixel:
  t = z * z
  z = fn1(t) + p
  |z| < 4
}

With fn1=ident it should render standard M-set

I suspect this is another bug/difference between the C parser and the assembly language parser.
