Just a uber simple way to generate a mesh from a height map.
This uses Image Manipulator, so its a bit too slow to be used all the time.
Also note Image manipulator is a bit quirky... The image must be resized, and flipped to work.
Plus this sets the distort map to 60x60, and that's pushing its limits. Finally its set to check values from 0 to 255... 100 is supposed to be max, 255(pure white) will be off screen.
