Change noVNC license to from LGPLv3 to MPL 2.0
The MPL 2.0 license is a "file-level" copyleft license vs the
"project-level" nature of the L/GPL. The intention of noVNC has
always been that it should be easy to incorporate into existing
projects and sites whether free/open or proprietary/commercial. The MPL
2.0 is designed for this sort of combination project but still
requires that any distributed modifications to noVNC source files must
also be published under the same license.
In addition, the MPL 2.0 allows the code to be used in L/GPL projects
(the secondary license clause). This means that any projects that are
already incorporating noVNC should not be impacted by this change and
in fact it should clarify the licensing situation (the exact
application of the L/GPL to web applications and interpreted code is
somewhat ambiguous).
The HTML, CSS, image and font files continue to be under more
permissive licenses (see LICENSE.txt). The included websockify python
code remains under a LGPLv3 license although the include/websock.js
file from the websockify component is now under MPL 2.0 as well.
Permission was received from other noVNC authors to make this change to their
code license on the following dates:
- Chris Gordon (UI): Jun 24, 2012
- Antoine Mercadal (DOM,*util.js): Oct 10, 2012
- William Lightning (UltraVNC repeater): Oct 10, 2012

include/vnc.js: dynamic load without document.write.
Instead of using document.write to load scripts, use createElement to
create and append script tags. document.write is problematic in a lot
of situation and in particular is not allowed in a Chrome
extension/packaged app.
Also, in webutil.js, instead of calling init_logging during parsing of
include/webutil.js, rely on the caller to do this. The problem is that
calling init_logging on parse tries to call Util logging functions and
the new model of dynamic load may not having Util loaded by the time
webutil is parsed.

ui.js: use localStorage/chrome.storage for settings.
Switch from using cookies to store setting to using localStorage (or
chrome.storage.sync if available in extension/app mode) for the
settings. Also refactor to make the initializing of the setting and
and loading of the UI to be more asynchronous.
Add routines to store/read settings in either localStorage or in
chrome.storage.sync (which is synchronized between browsers for
extensions/apps).
Before using chrome.storage.sync the initSettings routine must to
called setup the intermediate cache which speeds up access and allows
multiple setting changes to be coallesced to avoid hitting storage
change frequency limits/quotas.
Most note worthy changes:
- Pulls in web-socket-js 7677e7a954 which updates to IETF 6455 (from
Hixie)
- Binary support detection and use in include/websock.js
- Add ssl and unix target support
- Add multiple target support via config file/dir.
- Idle timeout exit

Fix grep pattern when searching for listening sockets
The current grep pattern matches also port numbers that match only
partially the given $PORT number; e.g., if $PORT is 6080, 60800 will
match as well.
While TCP listening sockets in the 60000-65535 range are rare, they
need to be handled as well. The problem is also present if the user
selects a shorter PORT value with the --listen command line argument.
Use a simpler method of enabling binary transfer over WebSockets. This
still presents the user of websock.js with a plain javascript array
for the receive queue data. However, if binary support is supported
and requested then the transfer will be raw frames instead of base64
encoded.
Lots of room for optimization here but for now correct is better than
fast.
Several changes including:
- binary/typed array support in websock.js
- unix socket support
- multiple target support via config file(s)
- prefer IPv6 option

License clarification: HTML,CSS,images,fonts under permissive licenses.
Clarify in LICENSE.txt that the noVNC core library is the part that is
LGPLv3 licensed. The HTML, CSS, images and fonts are separate from the
core library and can be modified and distributed with the noVNC core
but under their own license conditions.
HTML and CSS: 2-Clause BSD
Fonts: SIL OFL 1.1
Images: CC BY SA 3.0
In other words, you can modify the layout and appearance of of noVNC
to integrate with an existing or new web site or application without
having to publish the source for those modifications under the LGPLv3.
However, use of and modification of the noVNC core library (i.e. the
core Javascript that makes up noVNC) must still be according to the
LGPLv3.

included with noVNC and gave permission for this license clarification

rfb: Use the render queue for copyrect.
This will keep copyrect rendering actions in order with tight and tightPNG

they are mixed together).
Warning:
RAW, RRE and HEXTILE still use immediate render commands so there is
still the risk of out-of-order rendering if RAW, RRE, and HEXTILE are
mixed with tight and tightPNG. Copyrect will work with either because
the renderQ_push function will render copyrects immediately if they
are the only thing being pushed on the queue.

Move render queue processing to Display and use requestAnimationFrame
The imgQ code in RFB should be a generic rendering queue system in
Display.
The reason for the render queue in the first place is that images
loaded from raw data URI strings aren't immediately ready to display
so we have to wait for them to complete 'loading'. However, when data
URI images are mixed with other types of rendering actions then things
can get out of order. This is the reason for the rendering queue.
Currently this only keeps display actions for tight and tightPNG
related actions in order (because they use a mix of fills, raw pixel
data and data URI images).

Release down/pressed keys when window loses focus.
May window managers have a keyboard shortcut that switch away from the
current desktop (e.g. desktop switcher). Unfortunately, when this
happens, the meta/control keys that are used with the shortcut will
send a down event to the browser, but the up event will never be sent
because the browser no longer has focus at the point when the up event
happens. This can cause weird stuck key issues for VNC clients (not
just noVNC). To get around this, we try and detect when the browser
loses focus and release any keys that are on the keyDownList.
As an aside, if you run into this situation (in noVNC or another VNC
client), you can unstick the state by pressing and releasing the Ctrl,
Shift, Alt, etc.
