Also, this is why things like LBX and NX exist.  X is a terrible 
protocol to use over high latency connections.  These patches may make 
it as usable as TightVNC, but that still has to be pretty terrible.

I don't mind the patches that adjust encoding order or implement new 
encodings.  As long as it's in the spec, and we have evidence (via 
traces) that some servers behave better with a different encoding order, 
that's fine to me.

Introducing low-level X dependencies seems like a bad idea to me 
though.  It makes the code less portable because of platform specific 
hacks and it makes things generally less understandable.  If there's 
wide agreement that this is something we should do, I'll concede, but it 
doesn't seem right to me.
