Native endian. The format is defined in terms of bitfields in a 32-bit
integer. The 16-bit formats (such as r5g6b5) are also defined
similarly. The 24-bit formats are not.
So to convert to or from a particular on-disk image format, or one
which is defined in terms of bytes (as OpenGL does), you could use
ntohl() and htonl() from the sockets subsystem.
