 * Nano-X Core Protocol Header
 * 
 * These structures define the Nano-X client/server protocol.
 * Much of this has been modeled after the X11 implementation.
 * Note that all NX Protocol requests should have all data quantities
 * properly aligned. This is assured by hand-coding each NX request
 * structure.  Unlike Xlib, fixed size request structs don't have to
 * be a multiple of 4 bytes, since the length field is a byte count
 * and GetReq() automatically pads all requests to 4-byte boundaries.
 * Request structs for variable size data, however, must be hand-padded
 * to 4-byte alignment, as variable data starts after sizeof(structure).
 * Also, the hilength/length fields store the unaligned byte count, so
 * that extra code isn't required to de-crypt extra data size or
 * big packets.
 */
 
/*
 * The following is provided to allow limiting the maximum
 * request size that will be sent (not received) using this protocol.
 * The protocol allows for 2^24 byte maximum, but the
 * server currently allocates the MAXREQUESTSZ in a stack buffer.
 * Also, the client realloc's the request queue to 
 * the largest size asked for, and currently never reduces it.
 *
 * Routines like GrArea will split packets to be <= MAXREQUESTSZ
 * automatically.
 *
 * NOTE: MAXREQUESTSZ must be an _aligned_ multiple of 4, meaning
 * that MAXREQUESTSZ = (MAXREQUESTSZ + 3) & ~3.
