		const DynBitset &	a_ptsFlag,
		VecFlt &	a_smoothElevs
	)

Smooths a elevations based on max specified slope (a_maxSlope) preserving either the min or max based on a_anchorType.

Parameters

[in]	a_tin	Points and triangles defining the connectivity of the size function.
[in]	a_elevs	Array of the current elevations
