 * GuiControllerLayout.h
 *
 * A controller described as data: a silhouette made of rounded pieces and a
 * table of controls (buttons, sticks, triggers), each with a position, shape
 * and id. GuiControllerView draws any layout, lights controls up and
 * highlights them; supporting another controller means adding a table, not
 * drawing code. Control ids are the INPUT_BTN_* / INPUT_TRIGGER_* /
 * INPUT_THUMB_* bits from InputData.h, so an input state maps straight onto
 * what lights up. Platform-agnostic.
