Detailed Description

Draws a controller from a GuiControllerLayout and shows what is happening on it: controls light up while pressed, a chosen control is highlighted (optionally with a line from a list row to it), and sticks follow their position.

It is a picture, not a button: selection lives in the list beside it, and the list tells the view what to highlight.
