Jakob Botsch Nielsen b99d62047b Increase recover radius for unsampled heights ...

When the detail mesh sampling sees an unset height it previously tried
to recover by looking for heights of neighbors. When the heightfield was
not eroded this recovery would fail since the contour simplification
could mean that the nearest valid cell was further away than a neighbor.
We now walk adjacent cells in a spiral to find a height and do this
depending on the max simplification error.

Fix #153
