void R_Trace	(	vec3_t	start,
		vec3_t	end,
		float	size,
		int	contentmask
	)

Moves the given mins/maxs volume through the world from start to end.

Parameters:

[in]	start	Start vector to start the trace from
[in]	end	End vector to stop the trace at
[in]	size	Bounding box size used for tracing
[in]	contentmask	Searched content the trace should watch for
