distance property

double distance
final

A value between 0.0 .. 1.0, defaulting at 0.6, that places the "midpoint" for each color shading function in the Steps.

It is a percentage between the start and end of each step color to begin transitioning toward the color value with shadeFunction applied to it.

Imagine this represents the color red as a dark "shaded step" with distance ~= 0.5 (note: each color and stop in a FooShadedSteps is "quadruplicated", so this diagram accurately represents how each color will be divided):

|-----------------+++++++++++++++++++++++|
[RED]  . [RED]  . [MIDPOINT] . [DARK RED]

Then imagine this represents the same scenario but distance ~= 0.25:

|--------++++++++++++++++++++++++++++++++++++++++++|
[RED]  . [MIDPOINT] . [STILL BLENDING] . [DARK RED]
