A simple drawing abstraction

Draw is not intended for use in writing full GUI interfaces, rather it is a simple abstraction layer to allow for the creation of minimal UI elements such as status bars, menus and dialogs. Each Draw should also provide an acompanying DrawContext that impl that is used by consumers (such as the status bar) for actually drawing to the screen, which the parent Draw is responsible for resource management and mapping / unmapping the created windows.
