* Templates for the span/pixel-array write/read functions called via
- * swrast. This is intended for memory-based framebuffers (like OSMesa).
+ * the gl_renderbuffer's GetRow, GetValues, PutRow, PutMonoRow, PutValues
+ * and PutMonoValues functions.
*
* Define the following macros before including this file:
- * NAME(PREFIX) to generate the function name
+ * NAME(BASE) to generate the function name (i.e. add prefix or suffix)
+ * 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
- * STORE_RGB_PIXEL(P, X, Y, R, G, B) to store RGB values in pixel P
- * STORE_RGBA_PIXEL(P, X, Y, R, G, B, A) to store RGBA values in pixel P
- * FETCH_RGBA_PIXEL(R, G, B, A, P) to fetch RGBA values from pixel P
- *
- * Note that in the above STORE_RGBx_PIXEL macros, we also pass in the (X,Y)
- * coordinates for the pixels to be stored, which enables dithering in 8-bit
- * and 15/16-bit display modes. Most undithered modes or 24/32-bit display
- * modes will simply ignore the passed in (X,Y) values.
+ * STORE_PIXEL(DST, X, Y, VALUE) to store pixel values in buffer
+ * FETCH_PIXEL(DST, SRC) to fetch pixel values from buffer
*
- * For color index mode:
- * STORE_CI_PIXEL(P, CI) to store a color index in pixel P
- * FETCH_CI_PIXEL(CI, P) to fetch a pixel index from pixel P
+ * Note that in the STORE_PIXEL macros, we also pass in the (X,Y) coordinates
+ * for the pixels to be stored. This is useful when dithering and probably
+ * ignored otherwise.
