A method of calculating dwell that gives a continuous value, i.e. a value that varies smoothly rather than jumping from one integer to another. This allows for more variety in coloring algorithms.
The simplest method is to choose a large escape radius, then perform the ordinary iteration algorithm. Let Zn be the value of the iterate that exceeds the escape radius. The normal dwell value would be n (as shown in the pseudo-code in the escape-iterations article). The "continuous dwell" value is given by
D = n + log2(log2(|Zn|)) - log2(log2(EscapeRadius))
