Changes:
LodePNG always loads PNG in big-endian RGBA format. For this reason, when loading PNG files VVVVVV was specifying the format as ABGR and the conversion would then be performed by SDL. However, then running on big-endian machines, this conversion should not be performed at all, and the surface format should then be set to RGBA.
