which kept track on if it was open or not (it automatically closes after
1.5 seconds anyway).

moved it to where the other clipping functions are.

* Fixes #502 so that the viewport drag functionality can't get stuck

"jumping around". Enable/disable the button instead of show/hide on these
devices.

Fixed incorrect UI usage and minor updateState params errors in vnc_auto.html

Reverting most of commit cb3e4deb. The issue was not related to using keyboardinputReset.. the issue was infact a typo which was introduced in 3b8ec46f. I must be too tired..

* This fixes backspace when using the on-screen keyboard on Android

Removed old no longer existing vnc.js and added playback.js

Make noVNC compatible with Content Security Policies

* Disable local cursor when the browser doesn't support data uri

slip in PATH for 'npm test' as not everyone has karma

Throw exceptions from RFB constructor

Follow symbolic links in launch.sh

Previously, if an error was thrown from the Display constructor
in the RFB constructor, we would attempt to use `RFB#updateState`
to handle this.  However, `RFB#updateState` attempts to close
the WebSocket connection, which doesn't exist at this point.

In the constructor, it's probably just better to raise an exception
instead (making sure to clean up anything relevant).

Fixes #460

In e543525f, we switched to creating
a new RFB object on disconnect.  This caused issues, however, since
any errors were only displayed briefly before the new "loaded" text
was displayed instead.

Now, we create the RFB object on connect.  This essentially removes
the usefulness of the "loaded" state, but prevents the aforementioned
problem.

To facilitate this, the code which does detection of cursor URI support
was moved from this Display constructor (which now calls the new
function) into its own function, `Util.browserSupportsCursorURIs()`.

Fixes #467

Previously, in launch.sh, `$HERE` was the directory of `$0`.
However, if `$0` was actually a symlink, `$HERE` would be
wherever the symlink was, which could cause issues (for
example, the script wouldn't be able to local `$WEB` or
`$WEBSOCKIFY` properly).

Now, `$HERE` looks at whatever `$0` points at instead.

Closes #447.

Fix resize in Firefox on Android

* Renamed and reworked fbuClip to clippingDisplay
* Added tests for clippingDisplay
* Use the a noVNC_container which covers the entire page to get the full size
  (Fixes #463)
* Added maxWidth and maxHeight to the canvas which can limit the viewport size
* Only show either the canvas or the logo, hide one when the other is shown
* Always center the canvas (previously it was only centered when not clipping)
* Removed iOS specific "position-fixed" fixes and start calling setBarPosition
  on every resize
* Removed the noVNC_screen_pad

* Added better error handling in ExtendedDesktopSize
* Added helper function to share code with DesktopSize
* Update test.rfb.js to only check for error handling if we were the
  ones requesting the resize

Make the touch-keyboard code more robust through verifying that global variables are set before use.

Introduce Local Autoscaling

This commit adds two new addition scaling options.  Both options do
local scaling.  The first "Local Scaling", does both upscaling and
downscaling.  The second option, "Local Downscaling", only downscales.

This is based on work by @mightypenguin (with an additional bug
reported by @glazik12).

This commit updates the UI to allow for different
scaling modes.  The "resize" option was changed to
be a dropdown with the following options: "None" (nothing),
"Remote Resizing" (SetDesktopSize).

This commit makes Travis launch sauce connect, instead of
using karma to start Sauce Connect

Make Util.getPosition be relative to page

Commit 5108c463 caused a regression
in the case where scrolling is used -- getPosition return position
relative to the viewport, while getEventPosition expected a position
relative to the page.

As per
https://developer.mozilla.org/en-US/docs/Web/API/Element/getBoundingClientRect,
the fix for this is simply to add the `pageXOffset` and `pageYOffset` to
the output of `getBoundingClientRect()`.

Fixes #459.

This commit increases the browserNoActivityTimeout to 100s
(from the default of 10s) in an attempt to alliviate the
timeout issues that we are seeing.

This commit updates the test dependencies to the latest versions.

Fix disconnect/reconnect issues

Commit 155d78b3 prevented reconnections
from working properly.  This fixes that by creating a new RFB object
after disconnecting or failing.

Furthermore, this ensures that a new connection cannot be opened util
we've actually disconnected (either by timer or by receiving a `close`
event).

Closes #452

This commit removes the old debian packaging information, which is
out of date.  People who wish to create Debain packages for noVNC
are better off using the package information from the actual Debian
or Ubuntu packages.

Closes #453

Issue #449 pointed out that there were some files that were
missed in 6f514864.  This
fixes that.

Closes #449
Closes #450

When `utils/launch.sh` clones websockify, it can be cloned
into the incorrect directory, depending on how `utils/launch.sh`
is run.  This commit ensures that websockify is always cloned into
`utils/websockify`.

Somehow, `utils/websockify` itself manage to sneak back in to
6f514864.  This actually removes
it.
