-AddPoint takes an x and y location for the point, a size (required to start a line) and erase (whether the line is erasing from the map).  The size is the "width" value from [[DrawnMapFormat]].
+AddPoint takes an x and y location for the point, a width (indicates the start of a new line) and erase (whether the line is erasing from the map).  The width calculation is described in [DrawnMapFormat].
 
 FlushPoints writes out any values from PointsBuffer that have not already been sent to the engine.
 It would be called at the end of a drawing session.

 This one fills the map with solid land, and draws 3 circular erased points in it.
