20 * DrawableObject is the base object interface for objects that can be rendered to the screen.
21 * Note that objects derived from DrawableObject are passed between threads, and that care must be
22 * taken when modifying drawable parameters to avoid side-effects (for example, the DrawableFactory
23 * class can be used to generate fire-and-forget drawables).
