float shadow_halo	(	LampRen *	lar,

		struct ShadBuf *	shb,
		const float	rco[3],
		const float	dxco[3],
		const float	dyco[3],
		float	inp,
		float	mat_bias
	)

Determines the shadow factor for a face and lamp. There is some communication with global variables here.

Returns:

The shadow factors: 1.0 for no shadow, 0.0 for complete shadow.

Parameters:

shb	The shadowbuffer to find the shadow factor in.
inp	The inproduct between viewvector and ?
