* For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
* for pal8. This palette is filled in automatically by the function
* allocating the picture.
- *
- * @note
- * Make sure that all newly added big-endian formats have (pix_fmt & 1) == 1
- * and that all newly added little-endian formats have (pix_fmt & 1) == 0.
- * This allows simpler detection of big vs little-endian.
