int BoxTest	(	v16	x,
		v16	y,
		v16	z,
		v16	width,
		v16	height,
		v16	depth
	)

Performs a test to determine if the provided box is in the view frustrum.

Parameters:

	x	(x, y, z) point of a vertex on the box
	y	(x, y, z) point of a vertex on the box
	z	(x, y, z) point of a vertex on the box
	height	(height, width, depth) describe the size of the box referenced from (x, y, z)
	width	(height, width, depth) describe the size of the box referenced from (x, y, z)
	depth	(height, width, depth) describe the size of the box referenced from (x, y, z)

Returns:

non zero if any or all of the box is in the view frustum.

Examples:

Graphics/3D/BoxTest/source/main.cpp.

void BoxTest_Asynch	(	v16	x,
		v16	y,
		v16	z,

	z	(x, y, z) point of a vertex on the box
	width	(width, height, depth) describe the size of the box referenced from (x, y, z)
	height	(width, height, depth) describe the size of the box referenced from (x, y, z)
	depth	(width, height, depth) describe the size of the box referenced from (x, y, z)

int BoxTestf	(	float	x,
		float	y,
		float	z,
		float	width,
		float	height,
		float	depth
	)

Parameters:

	x	(x, y, z) point of a vertex on the box
	y	(x, y, z) point of a vertex on the box
	z	(x, y, z) point of a vertex on the box
	width	(width, height, depth) describe the size of the box referenced from (x, y, z)
	height	(width, height, depth) describe the size of the box referenced from (x, y, z)
	depth	(width, height, depth) describe the size of the box referenced from (x, y, z)

Returns:

non zero if any or all of the box is in the view frustum.

Examples:

Graphics/3D/BoxTest/source/main.cpp.

void BoxTestf_Asynch	(	float	x,
		float	y,
		float	z,
		float	width,
		float	height,
