- Add meta tag to vnc.html and vnc_auto.html so that if Chrome Frame
  is installed, it is used.

- Add detection to default_controls.js that shows a message with
  a Chrome Frame install link if the user is using a version of IE
  without Canvas support.

- Fix web.py so that requests have their connection closed after they
  are completed.  This has been a bug for a while but it prevents
  Chrome Frame from working because Chrome Frame doesn't activate
  until the initial request connection closes.

- Also, discovered node.js bug in base64 decoding. Added test case and
  filed https://github.com/ry/node/issues/issue/402

It mostly works, but it eventually gets an error from the target which
is probably due to missing support for re-assembly of client
WebSockets frames.

- With a strict doctype, the margin size needs a "px" suffix.

This is WebKit bug https://bugs.webkit.org/show_bug.cgi?id=46319

The workaround is to wrap Canvas render functions with a function that
sets a flush timer. The flush function sets the right margin and then
1ms later sets it back. This triggers the canvas to redraw with the
correct contents.

Two downsides:
- rendering is slower, but only on the busted versions of webkit.
  Correct and useful is better than fast and useless.
- There is a barely perceptible jitter of the control buttons because
  the canvas size is changing by one pixel.

To support this functionality, we also have to read out the exact
webkit version from the user agent in the render engine detection code
in include/util.js.

- Make sure that canvas exists (i.e. didn't throw an error) before
  trying to call canvas method get_canvas_uri.

- Typos in HTML render engine debug output.

If only --cert is specified then continue to assume both certificate
and key are in the same file (key first).

- pass CFLAGS and LDFLAGS in case one needs to use -m32
- link to libcrypto for _ERR_print_errors_fp
- __THROW is non-standard define it to nothing by default
- use b64_ntop and b64_pton instead of mangled versions, OSX doesn't mangle them in the same way
- access() takes two arguments!

- Split out ClientInitialisation state.

- In version 3.3 and 3.7, when the server has no auth (scheme
  1), then we should skip from Authentication to ClientInitialisation.

- Add wsproxy README.md in utils/ directory.

- Document how to build ssl module for python 2.5 and older in wsproxy
  README.

- Update browsers.md to note revision that have the webkit Canvas
  rendering bug: WebKit build 66396 through 68867 (Chrome/Chromium
  build 57968 through 61278).

If shared mode is false, then the server should disconnect other
connections before the current connection is allowed to proceed.

- Style caching gives a small performance speedup in firefox, but not
  much. Might not be worth complexity, but leave it in for now.

- rQwait checks the receive queue to see if there is enough data to
  satisfy the following request. If not it returns true (which is
  almost always translated into an immediate return false by the
  caller).

- rQwait is called quite a bit and this generally allows 4 lines to
  become 1 line where it is called.

- rQwait allows simplification of cuttext processing. No global
  tracking needed anymore.

Overall, about 60 lines less code.

DES is just used once during authentication and is not performance
sensitive so we save some space by generating and/or removing some
lookup tables. Also, shorten some very frequently used variables.

Shaves off about 100 lines.

 - util.js that contains essential functions
 - webutils.js that contains the GUI utility function.js

this helps to include noVNC in other project, especially Cappuccino Application
i

The decrypt functionality is never used so remove it. Also, we can
assume that we are always DES encrypting 16 characters which allows
several things to be simplified in DES.

Overall this removes about 80 lines of code.

- include/rfb.js: Keep track of the number of rects of each encoding
  type and print them out when we close a connection (if 'info'
  logging level).

- tests/vnc_perf.html: first pass at a noVNC based performance
  benchmark.

- utils/wsproxy.py: Fix the output of the record filename.

Read the render mode selected by canvas and report it in the initial
page loaded status message.

- include/util.js: Add type and desc field to conf_default routine.
  Make comment descriptions of settings into desc parameters that can
  be queried. Also, use set_FOO in conf_default to set or coerce the
  current setting so that we always have the right type for the value.

- include/rfb.js, include/default_config.js: add connectTimeout
  setting to address situations with slow connections that may need
  more than 2 seconds.

Yet another weird VNC server behavior: sending a failure and length
before the reason message. To calculated the length, the reason string
is already available, why not just send everything as one packet. Oh
well.

- include/canvas.js: When 'debug' logging, show browser detection
  values.
- test/canvas.html: Only restore the canvas to it's starting state if
  the logging level is not 'debug'.
- wsproxy.py: Append the session number to the record filename so that
  multiple sessions don't stomp on each other.

Update the browser detection code (from mootools) with a fix that
detects firefox 4.0 correctly.

Only clear canvas if log level is not debug instead of using
'#__debug__' in the URL.

Easier to reference from web site (gh-pages branch).

In Safari, local cursor rendering is corrupt. In firefox 3.6.10, local
cursor rendering causes a segfault. Probable that the .cur format is
not 100% compliant (even though it works in Chrome and firefox 3.5 and
firefox 4.0). So just disable it by default until I can figure out how
to address the problems.
