[megameter]

No advanced art process can avoid some amount of engineering, because the demand that is made is to measure and select with precision that which is to be edited.

When we use a mark-making tool like a pen, all that's happening is that we select the area being pressed to be darkened. Technique with those tools takes years to develop, and their full use comes in tandem with additional tools like rulers, prospekt, and stencils.

So when we add knobs and sliders and modes we are simply trying to describe those kinds of intents within a precise abstraction instead of a collection of simpler tools. It does go overboard in that nobody's going to adjust every knob presented.
