NAME
     glInterleavedArrays - simultaneously specify and enable several
     interleaved arrays


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


PARAMETERS
     format   Specifies the type of array to enable. Symbolic constants
              GLV2F, GLV3F, GLC4UBV2F, GLC4UBV3F, GLC3FV3F,
              GLN3FV3F, GLC4FN3FV3F, GLT2FV3F, GLT4FV4F,
              GLT2FC4UBV3F, GLT2FC3FV3F, GLT2FN3FV3F,
              GLT2FC4FN3FV3F, and GLT4FC4FN3FV4F are accepted.

     stride   Specifies the offset in bytes between each aggregate array
              element.

DESCRIPTION
     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 efficient than
     specifying the arrays seperately.

     If stride is 0, the aggregate elements are stored consecutively.
     Otherwise, 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 indicates
     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 follows is
     located at the first possible floating-point aligned address.

NOTES
     glInterleavedArrays is available only if the GL version is 1.1 or
     greater.

     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 glPushClientAttrib and
     glPopClientAttrib instead.

ERRORS
     GLINVALIDENUM is generated if format is not an accepted value.

     GLINVALIDVALUE is generated if stride is negative.
