glTexCoordPointer - define an	array of texture coordinates

	  void glTexCoordPointer( GLint	size,
				  GLenum type,
				  GLsizei stride,
				  const	GLvoid *pointer	)

	  size	   Specifies the number	of coordinates per array
		   element. Must be 1, 2, 3 or 4. The initial value is

	  type	   Specifies the data type of each texture coordinate.
		   Symbolic constants GL_SHORT,	GL_INT,	GL_FLOAT, or
		   GL_DOUBLE are accepted. The initial value is

	  stride   Specifies the byte offset between consecutive array
		   elements.  If stride	is 0, the array	elements are
		   understood to be tightly packed. The	initial	value
		   is 0.

	  pointer  Specifies a pointer to the first coordinate of the
		   first element in the	array.

	  glTexCoordPointer specifies the location and data format of
	  an array of texture coordinates to use when rendering.  size
	  specifies the	number of coordinates per element, and must be
	  1, 2,	3, or 4.  type specifies the data type of each texture
	  coordinate and stride	specifies the byte stride from one
	  array	element	to the next allowing vertexes and attributes
	  to be	packed into a single array or stored in	separate
	  arrays.  (Single-array storage may be	more efficient on some
	  implementations; see
	  glInterleavedArrays.)	 When a	texture	coordinate array is
	  specified, size, type, stride, and pointer are saved
	  client-side state.

	  To enable and	disable	the texture coordinate array, call
	  glEnableClientState and glDisableClientState with the
	  argument GL_TEXTURE_COORD_ARRAY. If enabled, the texture
	  coordinate array is used when	glDrawArrays, glDrawElements
	  glArrayElement is called.

	  Use glDrawArrays to construct	a sequence of primitives (all
	  of the same type) from prespecified vertex and vertex
	  attribute arrays.  Use glArrayElement	to specify primitives
	  by indexing vertexes and vertex attributes and
	  glDrawElements to construct a	sequence of primitives by
	  indexing vertexes and	vertex attributes.

	  glTexCoordPointer is available only if the GL	version	is 1.1
	  or greater.

	  The texture coordinate array is initially disabled and it
	  won't	be accessed when
	  glArrayElement, glDrawElements or glDrawArrays is called.

	  Execution of glTexCoordPointer is not	allowed	between	the
	  execution of glBegin and the corresponding execution of
	  glEnd, but an	error may or may not be	generated. If no error
	  is generated,	the operation is undefined.

	  glTexCoordPointer is typically implemented on	the client
	  side with no protocol.

	  The texture coordinate array parameters are client-side
	  state	and are	therefore not saved or restored	by
	  glPushAttrib and glPopAttrib.	 Use glPushClientAttrib	and
	  glPopClientAttrib instead.

	  GL_INVALID_VALUE is generated	if size	is not 1, 2, 3,	or 4.

	  GL_INVALID_ENUM is generated if type is not an accepted

	  GL_INVALID_VALUE is generated	if stride is negative.
