This is where to install headers to, not where to find headers to
build against. Toolchains should know where to locate their system
headers while non-system headers should be found using
pkg-config. Users with bizarre setups where the toolchain really
cannot find the system headers should set CPPFLAGS.

Patch originally by @KenMilmore on GitHub.

Add more checks and fix some callers to make sure that the server
core always has a valid screen layout configured.

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.

It now accepts this parameter, so make sure it is documented.

We disabled it in 0a0e582 since it didn't have support for resizing.
But it got that support in 242c5b2, yet we forgot to allow this
setting again.

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.

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.

We might have an offset in the area of the screen we're tracking,
so make sure that offset is included in the changes we report.

We might only be using part of the X server's screen, so make sure
the layout we calculate is contained within this part.

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.

Must be done in order to remove UNIX sockets etc.

Our main web site now supports https, so update all references.

Make things simpler by making this a part of the SDesktop interface
that always needs to be implemented.

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.

Applets don't work anymore so remove everything that has to do
with serving them.

Most layouts on Unix generate Meta for Shift+Alt but non-Unix clients
will send XK_Alt_*. This results in us picking some other key which
can confuse some applications.

Try to detect this scenario and map XK_Alt_* to XK_Meta_*.

We cannot assume endian-ness for the cursor we get from XFixes.
Adjust the algorithm to properly follow the specification.

We get a whole bunch of very tiny areas, which is very inefficient to
deal with. Instead create a rectangle around every "list" of connected
glyphs (usually each line).

There are some cases where the server state will not automatically
be updated on a change. A prominent one is when only RFB attributes
were changes (e.g. the screen ID) but nothing else. In that case
there is no actual change in the X server, so it never sends any
notification about change back to us.

x0vncserver might only be observing part of the display, so we need
to adjust any coordinates before we give them to the RFB core.

Function xorgGlxCreateVendor() is defined in glx_extinit.h, if this header is
not included, we might get either error or warning. This header also need to
be included after scrninststr.h header as it defines some structures used
in glx_extinit.h

In-server GLVND requires xorgGlxCreateVendor call from InitOutput.
DPMS functions were moved to another location and no longer need to be faked.
xserver120.patch is a copy of xserver119.patch with refreshed contexts.

Patch originally by Dag-Erling Smørgrav for University of Oslo.

The Xserver (at least Xorg 1.19) rejects RRSetCrtcConfig requests if
rotation is zero.

Makes the code more general and not directly tied to specifically
TCP sockets.

With the new unixcommon library we have things outside of common/,
so make the handling of out-of-tree builds more general.

Change Xserver screen through libXrandr. For complex configurations,
all outputs must have corresponding size modes. As a special case, if
the client requests a single screen with an odd size (for example when
adjusting the size of a non-fullscreen vncviewer), find a smaller
suitable mode, and reduce the framebuffer size as well.

This can be used to test if a layout if possible.

Better to avoid making unnecessary calls, but mainly we want to avoid
logging false errors.

For example, if we have earlier disabled an output because it was too
large for the framebuffer, we should prefer this output when
allocating new outputs.

Move the code that turn off unused outputs to the end.

Also, add support for checking the output connection state.

Apparently this is not necessary when using the internal API, but a
must with libXrandr.

This only matters when using clones, which we do not accept yet. This
patch is for completeness and to avoid future surprises.

Return error if no CRTC.

Screen is a Xvnc thing and not relevant for x0vncserver etc.

RANDR is mandatory since Xorg 1.7, which is the oldest version we
support.
