Stop utterly insane palette entry population.
Palette entries are always ABGR, regardless of platform endianness.
This change probably breaks big-endian platforms which, under the old approach,
had palette entries of the form RGBA (assuming I understood the code correctly).

Fix palette entry population some more. Hopefully, it's completely endian
agnostic now and still builds with GCC 4.4
