   Implementation inspired by node-drawille (https://github.com/madbence/node-drawille)
   * added color support
-  * added support for filled polygons
   * added text label support
   * general optimizations
-    -> more bit shifting/operations, less Math.floors
 
   Will either be merged into node-drawille or become an own module at some point
