VisEntities()

proto int VisEntities	(	vector	origin,
		vector	look,
		float	angle,
		float	radius,
		out IEntity	ents[2],
		int	maxents,
		int	fmask )

finds all visible entities (rought, according to a visibility. It is convinient for entitie selection where we want to do more precise visibility test)

origin	- position it is looked from
look	- look direction
angle	- view angle (usuably 90). -1 if we do not care about the view angle
ents	- array to which entities will be stored
maxents	- length of the array (prevents overflowing the array)
fmask	- flag mask (SetFlags()). Entity must have all flags set. it is possible to use reserved flags like EntityFlags.USER1, EntityFlags.USER2, EntityFlags.USER6 for fast finding of entities in custom categories
