Stage 0; perlin works, pathing works... think it cheats and doesn't find a 'best'; continues with backscan after completion (fast complete)
Stage 1; path is by slope; going up is harder than going down... does a wide scan; h1() is too short
Stage 2; path is by height; it prefers to take the lowest path available. (started tracking known 'paths')
Stage 3; Path is by slope. black->blue->red->white is height, and prefer least 'up' path.
Stage 4; Natural ladscape textures - find A*path across flattest median - min and max limit the path...to make it effecitvley untraversable... could get locked and not draw a path... please refresh- it doesn't know how far it got either to try again(?)
Stage 4; (scaled fdifferently, different noise tweak...\\

Perlin 3D attempt to build a sphere map that wraps at the far ends. Ended up distroting the polar patch more than desired
