Make #numiter readable?

Currently #numiter is readable only in the Final section of a ucl coloring formula. It is not even readable in the ResultIndex function of a ulb Coloring formula, where one might expect to be able to use it.

If #numiter were readable in any coloring formula, whether in a .ucl or. ulb file, some interesting coloring options would be available. For example, if coloring according to distance from a circle, the circle radius could vary with #numiter.

Is there some internal UF reason for keeping #numiter not readable?

The value is not readily available during calculations: like most fractal software, UF uses a downward iteration count (let's call his remaining), initialized to #maxiter, and stops when it reaches zero. Then it sets #numiter=#maxiter-remaining before calling the final section. You could pass this value to a coloring plug-in.

The Coloring class in common.ulb has m_Iterations as a class member. Am I correct in thinking that m_Iterations should be the same as #numiter? This is available in all the classes that descend from Coloring.
