mixing up horizontal and vertical, chapter #3043
first implementation of navmesh aster algorithm that works, albeit not optimal yet
adjustments to navmesh demo
split up path rendering code
change demo grid a bit so it is easier to open different paths moving the obstacles
fix bug in estimated cost function + utility function for path
show multiple paths
better pallet for drawing navigation mesh
tweak demo grid a bit for nav mesh edge cases
fix bug with cost calculating in navigation mesh + extra output for debugging
add third path
fix bug with cost where we apparently have to take into account the +1 for the distance between parent end pos and start position
remove debug messages
