In noticed the standard DE method for Mandelbrot set is wrong: it erroneously updates dz after z.
I thought it was easy to fix, just save old value of z in ufm file and use that in the DE formula.
So in the ufm file:
loop:
  zo = z
  z = z^@power + #pixel
and in the ucl file:
loop:
  dz = @power * zo^(@power-1) * dz + 1

But it seems the coloring code does not see the zo value, how can I make the variable zo in the ufm file visible in the ucl file?
There is nothing about scope in the docs.
