    9. 

  9. -D occlude				To test occlusion culling/clipping
    10. 

  10. -D occludeEarlyOut		Whether to skip further raycast jumps if a wall covers the entire height of a screen
    11. 

  11. -D clippedBottoms		Whether to clip the bottom edges of walls during occlusion. (instead of drawing it's entire height)
    12. 

  12. -D noMaxHeight			If enabled, uses a map with no building height limits. 
    13. 

  13. -D testPosition			To start at a recorded starting position/angle based on code ( see Start() );
    14. 

  14. -D debugView			To turn on debug view at the beginning ( see Start() ) which allows one to view surfaces transparently.
