dead links and bitrot
Two minor issues:
This script is written in python two which is depreciated, and should be rewritten in python three, but I have so far been successful in not learning python. :-) to simplify debugging I have clarified that it needs a python two interpreter.
This script downloads an old version of mesa (an update may be appropriate), unfortunately the release candidate previously specified is no longer available, so an update to the next released version was made.

Require all SMsgWriter caller to check capabilities
Make the API consisitent by requiring the caller to check what the client
supports before calling any of the write* functions. This avoids the
confusion that the functions might not always do anything.

Always send current screen layout to client
This is what the protocol requires, rather than sending what the
client specified in the request. This should be the same in practice
except for failures and possibly some races.

Increase range of ComparingUpdateTracker statistics
32 bits are not enough to keep track of all the pixels that might
flow through the system. Expand things to 64 bits, which should cover
all reasonable uses.

Avoid using "fake" key codes
There is a range of key codes that are never sent by a real keyboard
and are therefore used by layouts to hide "fake" mappings. Make sure
to only use these as a fallback as some applications get confused
when they see these codes.

Abort unsafe lossless refresh early
We need to check earlier if we are going to send this refresh or
not. Otherwise we send out pings pointlessly, and we also stall
the request loop with a client as we clear the requested region
without actually sending an update message.
Prevent rendering uninitialized Pixmap contents on X11
The Pixmap is filled in as updates from the server arrive. Before the first full update, it would contain undefined contents, which would be rendered onto the ViewPort.
Clearing the Pixmap is only done on startup and when changing the server resolution, so it's not performance critical.

Get rid of SocketServer::checkTimeouts()
It doesn't belong on each socket server object as timers are global.
Force implementations to call the Timer system directly instead,
avoiding any middle men.

Properly terminate server on timeouts
Do a proper cleanup when one of the termination timeouts trigger
rather than just exiting on the spot. This makes sure we don't leave
stray stuff around, e.g. unix socket files.

Change exit timeouts to timers
This makes them more consistent with everything else, which makes
things clearer and also allows them to handle some corner cases
(e.g. only firing once).

Fixed handling of AltGr from Windows' touch keyboard
We need to test this always in order to catch Ctrl+AltGr, and to

Move client attributes out of ServerParams
ServerParams should contain the server state and not information about

Merge client resize capabilities
No need to have one setting for each extension. All the client code
needs to indicate is if it supports resize. The common code can then
map this to relevant extensions.

Make arguments explicit in all message writer methods
Make sure all methods only write what is given as arguments, and

Let CMsgHandler::serverInit() handle initial set up
Avoid using the callbacks used for runtime changes for the initial
setup. They weren't really useful anyway as you could not allocate
a framebuffer without also knowing the pixel format. So make things
more clear by letting serverInit() get the initial settings.

Encapsulate screen layout storage in ConnParams
Avoid direct access to the screen dimensions and layout so that we

Inherit SocketServer directly from VNCServer
This makes VNCServer a sufficiently complete interface that callers
don't need to know about the specific implementation (VNCServerST

that outrageous.

There is some client coordination needed which is better encapsulated
