       glInterleavedArrays  - simultaneously specify and enable several inter‐
       leaved arrays

       void glInterleavedArrays(
	       GLenum format,
	       GLsizei stride,
	       const GLvoid *pointer );

       Specifies the type of  array  to	 enable.  Symbolic  constants  GL_V2F,
       GL_V3F,	   GL_C4UB_V2F,	    GL_C4UB_V3F,    GL_C3F_V3F,	   GL_N3F_V3F,
       GL_C4F_N3F_V3F,	    GL_T2F_V3F,	     GL_T4F_V4F,      GL_T2F_C4UB_V3F,
       GL_T2F_C3F_V3F,	     GL_T2F_N3F_V3F,	  GL_T2F_C4F_N3F_V3F,	   and
       GL_T4F_C4F_N3F_V4F are accepted.	 Specifies the offset in bytes between
       each aggregate array element.

       glInterleavedArrays()  lets  you	 specify  and enable individual color,
       normal, texture and vertex arrays whose elements are part of  a	larger
       aggregate  array	 element. For some implementations, this is more effi‐
       cient than specifying the arrays separately.

       If stride is 0, the aggregate elements are stored consecutively. Other‐
       wise,  stride  bytes occur between the beginning of one aggregate array
       element and the beginning of the next aggregate array element.

       format serves as a ``key''  describing  the  extraction	of  individual
       arrays  from  the aggregate array. If format contains a T, then texture
       coordinates are extracted from the interleaved array.  If C is present,
       color  values  are  extracted.  If N is present, normal coordinates are
       extracted. Vertex coordinates are always extracted.

       The digits 2, 3, and 4 denote how many values are  extracted.  F	 indi‐
       cates  that  values  are extracted as floating-point values. Colors may
       also be extracted as 4 unsigned bytes if 4UB follows the C.  If a color
       is  extracted  as 4 unsigned bytes, the vertex array element which fol‐
       lows is located at the first possible floating-point aligned address.

       glInterleavedArrays() is available only if the GL  version  is  1.1  or

       If  glInterleavedArrays()  is called while compiling a display list, it
       is not compiled into the list, and it is executed immediately.

       Execution of glInterleavedArrays() 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.

       glInterleavedArrays() is typically implemented on the client side.

       Vertex  array  parameters  are  client-side state and are therefore not
       saved or restored by glPushAttrib() and glPopAttrib(). Use glPushClien‐
       tAttrib() and glPopClientAttrib() instead.

       When  the  GL_ARB_multitexture extension is supported, glInterleavedAr‐
       rays() only updates the texture coordinate array for the active	active
       texture	unit.  The  texture  coordinate state for other client texture
       units is not update, regardless if they are enabled or not.

       GL_INVALID_ENUM is generated if format is not an accepted value.

       GL_INVALID_VALUE is generated if stride is negative.
