      fill(0, 255, 0);

Description

This method will return true if the Grip is selected by the user, and false if not. A Grip that is not selectable is “active” only as long as the mouse is pressed on that Grip. A Grip that is selectable is “active” once the mouse is pressed on that Grip, and until something else is pressed.
