void ColorMap::Add	(	float	elev,
		const RGBi &	color
	)

Add a color entry, keeping the elevation values sorted.

void ColorMap::GenerateColors	(	std::vector< RGBi > &	table,
		int	iTableSize,
		float	fMin,
		float	fMax
	)		const

Generate an array of interpolated colors from this ColorMap.

Parameters:

table	An empty table ready to fill with the interpolated colors.
iTableSize	The desired number of elements in the resulting table.
fMin,fMax	The elevation range to interpolate over.
