try to use a 8888 texture format which will result in only a memcopy in mesa's texstore functions whenever possible for r200 and r300. r200 can use hw formats argb8888, rgba8888 and abgr8888 (or the opposite on big endian), r300 can use argb8888, bgra8888, rgba8888 and abgr8888 regardless of endian, as it supports free component swizzling.
