  *   NAME(BASE)  to generate the function name (i.e. add prefix or suffix)
- *   FORMAT  must be either GL_RGBA, GL_RGBA8 or GL_COLOR_INDEX8_EXT
+ *   RB_TYPE  the renderbuffer DataType
+ *   CI_MODE  if set, color index mode, else RGBA
  *   SPAN_VARS  to declare any local variables
  *   INIT_PIXEL_PTR(P, X, Y)  to initialize a pointer to a pixel
