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.
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).
This makes VNCServer a sufficiently complete interface that callers
don't need to know about the specific implementation (VNCServerST
currently). And assuming that all servers will use sockets is not
that outrageous.
Removed the last parts of VNCSConnectionST's back door in to
VNCServerST and let the parent class fully handle coordination of
clients, and access to the desktop.
There is some client coordination needed which is better encapsulated
inside VNCServerST. This also helps hiding the desktop from the
individual clients.
Force queryConnection() to always call back to approveConnection()
rather than return special values. This makes the flow easier to
follow as it will be the same in all cases.
We don't want to waste bandwidth on the lossless refresh if we might
need that bandwidth for a normal update. Try to estimate how much
data we can safely send without interfering.
No need to run all the update machinery when there is no client
connected.
This commit also cleans up the stop handling a bit by moving it to
its own method.
This redesigns the old "deferred updates" mechanism in to a frame
clock that governs how often updates are sent out. The goal is still
the same, to aggregate updates and avoid pointless updates, all in
the name of efficiency. This model should however be more robust
against delays that sometimes causes us to miss the desired rate.
Use PixelBuffer objects as the interface for encoders and decoders
This avoid a lot of unnecessary middle men. This also pushes the
responsibility for pixel format conversion into the encoders and
decoders. The new bufferFromBuffer() is used for direct conversion,
rather than PixelTransformer/TransImageGetter.
Add a magical cursor framebuffer class for handling when you
want to render the cursor on the server side. Keeps the cursor
specific magic in one contained place.
Gets rid of a loooot of code and complexity.
Colour map clients are still supported through an
automatically generated map, but we lose the ability to
develop a client or server that uses colour maps
internally.
Fix a race condition where we might get updates thrown at us right after a
framebuffer switch, but before we've been given the pointer to the new
framebuffer.

Make the comparing update tracker a bit more flexible. It can now be in an
"auto" state where it will be enabled until we deem that the client is better
of without it (currently triggered by explicitly stating a low compression
level).

Clean up the interface for VNCSConnectionST. Entry points are more apparent
and the data flow is now more strictly aimed towards this connection class.

It has some warts, but should be feature complete. Most of the magic happens
in the desktop class though.

Remove the "video" feature and its associated custom JPEG handling.
Having the client specifiy the video region is conceptually wrong
and a problem like this should be handled by better encoding selection.

Implemented support for DesktopName pseudo encoding, which allows
updating the desktop name on the fly.
Tested in ThinLinc since 2008-01-07.

[Enhancements, refactoring] Rationalized functions to control video
rectangle selection and default video rectangle. Added more logging and
improved error checking in the related code.

Passing VideoArea parameter to VNCServerST object. VNCServerST saves the
rectangle but does not use it yet.
does not do anything more.

Restored the functionality of the VideoPriority parameter. This time, it
should work correctly even over slow networks, when update requests go less
frequently than polling cycles. This version does not give any special
meaning to the value 0, it is equivalent to 1.
