| 2 * functions), and finally output to one (or more) of the state tables (the event stream). | |
| 3 * | |
| 4 * Adjuster and other event functions should have a format to fit the ES_X_Func types, for X is B | |
| 5 * (button event), A (axis event) or M (mouse relative motion event or joystick ball event). | |
| 6 * Adjusters should call (an) output function(s) of any type with their output(s). | |
| 7 * | |
| 8 * To control which adjusters get called and pass parameters, a stack is used. | |
