Nice. Looks like this is something one could work on. But yes, it
does not cover the compression but at least provides a good basis
for the initialization stuff for different screen modes.

But this is a joke, right?


/** Constant used for deciding if a host is big- or little endian.
 */
const uint32_t endian = 1;

/** Return non-zero if the host is big endian or zero if the host is 
little endian.
 */
#define IS_BIGENDIAN() ((*(char*)&endian) == '\0')

/** Convert a 32 bit little endian value into a host byte-order value.
 *
 *  @param  val  Little-endian 32 bit value to convert.
 *
 *  @return  Value in host byte order.
 */
#define LETOHL(val) (IS_BIGENDIAN() ? swap_endian_l(val) : val)

Runtime access to this "endian" constant on every LETOHL macro?

Sigh.

Have a nice day -- gotta get the usbvideo.class working before I have
time to spend on the DisplayLink stuff...
