template<typename SampleAt >

double bilinearAtUV	(	int	w,
		int	h,
		double	u,
		double	v,
		SampleAt	at
	)

Bilinear sample at a unit-UV position within a w x h sample grid (origin NW corner), sample-center convention, clamped at grid edges. at(x, y) returns the sample value as double.

The one shared interpolation for all elevation samplers: cross-source vertex identity requires bit-identical arithmetic, so samplers must go through this template rather than reimplementing it.
