I recently had this discussion with Daniel where I didn't want to use igt_drm_format_to_bpp() because it uses the format_desc array, and igt_fb currently assumes that all the format_desc formats have a matching valid Cairo format, so I wouldn't be able to easily add formats such as ARGB2101010. The function that has the assumption mentioned above is igt_get_all_formats: its current users call igt_get_all_formats, and then call cairo-dependent functions, such as igt_get_cairo_ctx on the returned formats. In order to document the current behavior and prevent any problems in case we start adding new formats without matching Cairo versions to format_desc, rename igt_get_all_formats to igt_get_all_cairo_formats and make it explicitly check for CAIRO_FORMAT_INVALID.
