`     6 A simple example is given below.  Note that Drawn maps use an area of 4096x2048.  The examples below are static, but obviously this could be used for a random map variation - for example, simulating the Cave map by doing the fill below, then drawing random tunnels using circles that shift their course smoothly.`
