not TCP based, without having VNCSConnectionST.cxx trying to call
setsockopt() on a non-socket.

Avoid corner case of applications rendering at frame rate
There is a problematic corner case where an application is updating
at exactly the same rate that we're sending update. In that case we
may miss updates regularly, getting a very uneven final frame rate.
Avoid this by introducing a slight offset when we start updating.

Push query connect timeout back in to Xvnc
It was moved to the common code in f8e3b34c6, but it was unreliable
because the state could sometimes get out of sync. Push it back in
to Xvnc since it isn't necessarily something all servers will have.

Switch back to low resolution mode on macOS
This is a revert of 6c0181c. Testing showed that we got a big
performance hit by enabling this, and we also saw some graphical
artifacts. More work is needed before this can be enabled by default.

Release pointer grab when cursor leaves window
We don't need the grab any more if the pointer cannot click on our

rfb_win32: Use scan codes if available
If scan codes are available using QEMU Extended Keyboard Messages
from clients, use that to inject scancodes directly into the
system using the SendInput API.
No conversion is needed as Windows uses the same scancode encoding.

Respect modifiers in x0vncserver
Using XKeysymToKeycode() often gives the incorrect keycode as it
doesn't respect the current modifier state. Use XKB to find the
proper key instead.
This however also means that we need to track the mapping for all
pressed keys to make sure we know the correct keycode when it is
time to release the key.

Fully implement support for alpha cursor pseudo encoding.
Alpha cursors are not supported in java on Windows so disable
it in that case. Ideally it would be nice to be able to test
whether or not the client OS supports it, but at the moment
MS Windows is the only one that I'm aware of that doesn't.

Fixed issue where CLI paramters specified as "-param value" caused
a java.nio.BufferOverflowException while the same parameter specified
as "-param=value" worked fine.
x0vncserver: Use Xfixes to display cursors if available
https://github.com/TigerVNC/tigervnc/issues/361
This is a simple implementation that refetches and transforms the cursor
image every time it changes, and doesn't use the cursor naming functions
of the XFixes extension to save & cache cursor images.

Increase default pointer event interval
Some systems (e.g. macOS) send massive amounts of pointer events, so
we need to start rate limiting things to something sensible by default.
One event per screen refresh should be more than sufficient.
Add a new parameter 'alertOnFatalError' which guards
the displaying of the GUI alert on fatal errors, and
thus when false just gives the textual error.
Now I can do:
while true
do
vncviewer alertOnFatalError=false vm:0
sleep 1
done
and it'll reappear when my VM appears without me getting error
dialogs.
