       glTexCoordPointer - define an array of texture coordinates

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

       Specifies  the number of coordinates per array element. Must be 1, 2, 3
       or 4. The initial value is 4.  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 GL_FLOAT.  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.  Specifies
       a  pointer  to  the first coordinate of the first element in the array.
       The initial value is 0.

       glTexCoordPointer() specifies the location and data of an array of tex‐
       ture  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 implementa‐
       tions;  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  glEnable‐
       ClientState()  and  glDisableClientState()  with	 the  argument GL_TEX‐
       TURE_COORD_ARRAY. If enabled, the texture coordinate array is used when
       glDrawArrays(),	glDrawElements(), glDrawRangeElements() or glArrayEle‐
       ment() 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

       The  texture  coordinate	 array	is  initially disabled and it won't be
       accessed	 when  glArrayElement(),   glDrawElements(),   glDrawRangeEle‐
       ments(), 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

       glTexCoordPointer() is typically implemented on the client side with no

       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.

       When  the  GL_ARB_imaging  extension  is supported, glTexCoordPointer()
       updates the texture coordinate array state of the active client texture
       unit, specified with glClientActiveTextureARB().

       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 value.

       GL_INVALID_VALUE is generated if stride is negative.
