*
* Define the following macros before including this file:
* 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
* INC_PIXEL_PTR(P) to increment a pixel pointer by one pixel
