Detailed Description

Each drawable has a geometry specification read from the lobot config file. A geometry specification consists of the (x,y) coordinates of the drawable's top-left corner within the Robolocust main window and a [width, height] pair in pixels with width going to the right and height going down (exactly like X Window geometry specs).

In some situations, we may want a drawable to be active, i.e., added to the main window, so that it can process keyboard input but not visible, i.e., the drawable doesn't really draw anything (perhaps it simply renders overlays on other drawables). To make a drawable invisible, simply set its dimensions in its geometry to negative quantities.
