       glColorPointer - define an array of colors

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

       Specifies  the number of components per color. Must be 3 or 4. The ini‐
       tial value is 4.	 Specifies the data type of each  color	 component  in
       the  array.  Symbolic  constants	 GL_BYTE,  GL_UNSIGNED_BYTE, GL_SHORT,
       accepted.  The  initial	value  is GL_FLOAT.  Specifies the byte offset
       between consecutive colors. If stride is 0  (the	 initial  value),  the
       colors  are  understood	to be tightly packed in the array. The initial
       value is 0.  Specifies a pointer to the first component	of  the	 first
       color element in the array.

       glColorPointer()	 specifies  the location and data of an array of color
       components to use when rendering.  size specifies the number of	compo‐
       nents  per  color, and must be 3 or 4.  type specifies the data type of
       each color component, and stride specifies the  byte  stride  from  one
       color  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	color  array is specified, size, type, stride, and pointer are
       saved as client-side state.

       To enable and disable the color array, call  glEnableClientState()  and
       glDisableClientState()  with  the  argument GL_COLOR_ARRAY. If enabled,
       the  color  array  is  used  when   glDrawArrays(),   glDrawElements(),
       glDrawRangeElements(), or glArrayElement() is called.

       glColorPointer() is available only if the GL version is 1.1 or greater.

       The  color  array  is  initially disabled and isn't accessed when glAr‐
       rayElement(),  glDrawArrays(),  glDrawRangeElements(),  or   glDrawEle‐
       ments() is called.

       Execution  of  glColorPointer() 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

       glColorPointer() is typically implemented on the client side.

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

       GL_INVALID_VALUE is generated if size is not 3 or 4.

       GL_INVALID_ENUM is generated if type is not an accepted value.

       GL_INVALID_VALUE is generated if stride is negative.
