With last_rect, the rects count can be high until a last_rect
pseudo-encoding is received which messes with the timing stats. So
count up the number of pixels rendered and show timing after the pixel
count reaches the width*height of the screen.

Add a helpful popup/panel message for when noVNC is used at
kanaka.github.com (e.g. where novnc.com redirects).

Addresses: https://github.com/kanaka/websockify/issues/29

I.e. if the page is https:// then the WebSocket encrypt setting will
default to wss:// (TLS encryption).

Note that since noVNC settings are saved in cookies, this will only
affect first load. If you have already loaded the page, then the
encrypt setting will be whatever you last set it to.

add last rect special encoding; fix tight fill subencoding color handling; fix mono indexed rect handling

Issue: https://github.com/kanaka/noVNC/issues/118
Reporter @maxnet also found and suggested the fix.

Probably could be more intelligent/generic by keying off the depth
sent by the server, but this will do for now.

Switched to using: http://www.jshint.com/

Pull from websockify: 008a5118e728.

Should address issue https://github.com/kanaka/noVNC/issues/107

- Also add ability to force use of web-socket-js using
  window.WEB_SOCKET_FORCE_FLASH

- in websock.js, for rQshift*, assume length is the full length if not
  specified.

Also add commented out web-socket-js debug variable in
include/websock.js

Resolve issue: https://github.com/kanaka/noVNC/pull/101

Based on proposal from @mightpenguin:
Matthew Balman <emperor@mightypenguin.org>

If view_only option is set then do not send mouse and keyboard events.
This is not a secure/enforced way to make a client view only. To
enforce view only at the server, most VNC servers support setting
a view only password.

Opera presto engine version detection is broken. For now, just return
true or false. That should cover most cases.

- Remove the images using the old font.

- Simplify the naming of the new control bar icon images.

- Change keyboard input type to 'email'. 'url' type doesn't have
  a space bar.

- Some clarifications to main LICENSE.txt file.

- CSS highlighting of buttons when selected.
- Keyboard button tweaked to allow show/hide toggle of keyboard.

and also in case Internet connection is flaky or unavailable.

Move viewportChange(), getCleanDirtyReset(), absX() and absY() to the
public API section. Also add some function comments.

Display API change:
    - getTile -> startTile (no longer returns a tile)
    - setSubTile -> subTile (drop img/tile first parameter)
    - putTile -> finishTile (no longer takes img/tile paramter)

The Display tile logic uses canvas image data directly and
caches/reuses a 16x16 imageData tile (for other sizes, the tile is
create for each call). This gives a 30% speedup on Chrome
13 (and no significant change for Firefox 3.6/4.0).

Other:

- Remove rgbxImageFill and cmapImageFill routines.

- Simplify constructor tests and just error if createImageData is not
  supported by canvas instead of .

- Remove webkit canvas bug workaround that effects Chrome 7. Chrome
  7 usage share is now less than 0.5 percent and the workaround is
  ugly. Drop the function wrapping in the constructor and the canvas
  flush() routine.

- Remove support for getImageData (Opera 11+ now required)

Update browser support list:

    - Chrome 8+ (really any except 7)
    - Firefox 3.6+
    - Safari 4+
    - Opera 11+
    - IE9+
    - iOS 4.2+

- Make sure that on iOS the clipping setting is always forced to be
  enabled.
- Hide the showKeyboard button unless connected.
- Use the URL text entry method and disable autocorrect and
  autocapitalize in the show keyboard input box.

Cleanup:

- remove unused changeViewportMeta function from include/ui.js
- remove some debug output and debug CSS.
- rename panel toggle functions and put them in same location in the
  code.
- refactor some code from updateState to updateVisualState routine
  (renamed from updateSettingsState).

API changes (forward compatible):

- Display: add 'viewport' conf option to turn on and off viewport
  mode.
- RFB: add 'viewportDrag' option to enable/disable viewport dragging
  mode.

Other:

- Add clip mode setting to default UI. For touch devices, clipping is
  forced on.
- Use CSS media queries to adjust visual elements based on screen
  size. Especially disconnected logo size/position and button text size.
- Catch page unload while connected and give a confirm dialog.
- Change mouse button selector to a single button that changes between
  ' ', 'L', 'M', 'R' when clicked (empty means mouse is just being
  moved and doesn't send clicks).
- include/ui.js:setViewClip() routine sets the clipping of the
  viewport to the current size of the viewport area (if clipping is
  enabled).
- include/ui.js:setViewDrag() toggles/enables/disables viewport
  dragging mode.
- Add several images for the UI and for Apple devices:
    - images/clipboard.png: clipboard menu icon
    - images/connect.png: connect menu icon
    - images/disconnect.png: disconnect button icon
    - images/keyboard.png: show keyboard button
    - images/move.png: viewport drag/move toggle button
    - images/settings.png: settings menu icon
    - images/screen_320x460.png: iOS app/desktop link start image
    - images/screen_57x57.png: iOS app icon
    - images/screen_700x700.png: full size noVNC image
