Remove support for non-HTML5 browsers.
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)

Fix window/document sizing in firefox.
Another firefox issue is that height: 100% is calculated as 100% of
the containing element even when the containing element is the window.
This means that the size of any sibling element shifts the window size
down by that much and causes the vertical scroll bars to appear. This
doesn't happen in Chrome.
- So instead, put a pad element inside the noVNC_screen element that
is the size of the control bar. This is hidden by the control bar,
however, it causes things to be sized correctly.

Viewport handling in include/display.js
Part of mobile device support:
https://github.com/kanaka/noVNC/issues/48
The Display object is redefined as a larger display region with
an equal or smaller visible viewport. The size of the full display
region is set/changed using resize(). The viewport is set/changed
using viewportChange().
All exposed routines that draw on the display now take coordinates
that are absolute (relative to the full display region). For example,
the result of fillRect(100, 100, 10, 10, [255,0,0]) will appear in the
canvas at (0,0) if the viewport is set to (100,100).
Details:
- Move the generic part of the viewport code from tests/viewport.html
into include/display.
- Add two new routines to the Display interface:
- viewportChange(deltaX, deltaY, width, height)
- This adjusts the position of the visible viewport and/or the
size of the viewport.
- deltaX and deltaY specify how the position of the viewport
should be shifted. The position of the viewport is clamped
to the full region size (i.e. cannot outside the display
region).
- The clean and dirty regions of the display are updated based
on calls to this routine. For example, if the viewport width
is increased, then there is now a dirty box on the right
side of the viewport. Another example, if the viewport is
shifted down and to the left over the display region, there
are now two dirty boxes: one on the left side and one
on the bottom of the viewport.
- getCleanDirtyReset()
- This returns an object with the clean box and a list of
dirty boxes (that need to be redrawn).
{'cleanBox':
{'x': x, 'y': y, 'w': w, 'h': h},
'dirtyBoxes':
[{'x': x, 'y': y, 'w': w, 'h': h}, ...]
}
- The coordinates in the clean and dirty boxes are absolute
coordinates (relative to the full display region) but they
are clipped to the visible viewport.
- Calling this function also resets the clean rectangle to be
the whole viewport (i.e. nothing visible needs to be redrawn
dirty) so the caller of this routine is responsible for
redrawing any

Add a viewport example/test.
Tested with an iPad 2.
This example shows a 400x200 viewport of an 800x400 display.
It tries to be intelligent about how much it redraws. It copies what
it can, and then when the user releases the mouse, it redraws the
"dirty" areas that were newly revealed.

Touch events and mouse button selectors.
First crack at supporting touch screen for devices like Android and
iOS tablets. Part of https://github.com/kanaka/noVNC/issues/48.
This change detects touch screen support and uses the touchstart,
touchmove, touchend events in place of the normal mouse events.
In order to support middle and right mouse clicks, if the device is
a touch device, then three toggle buttons are added to the UI
representing the left, middle and right mouse buttons. These select
which mouse button will be sent when the screen is touched. All the
buttons can be toggled off, in which case then the touch events only
move the mouse cursor rather than sending a mouse down and mouse up
for touchstart and touchend events respectively. This allows fairly
full control with the mouse on touch screens.

Fix ordering of tightPNG fills.
This addresses issue #65:
https://github.com/kanaka/noVNC/issues/65
When tightPNG encoded rects were received, any fill types were
immediately drawn to the canvas while images (PNG, JPEGs) were queued
for loading. This can cause screen corruption when things are changing
rapidly due to the misordering of fills vs images.
Also, remove the onload setting in each image on the queue and instead
decrease the tight image queue scanning interval (to 40ms or 25
scans per second).
The reocrd parameter will turn on recording of all messages sent
to and from the client. The record parameter is a file prefix. The
full file-name will be the prefix with an extension '.HANDLER_ID'
based on the handler ID.

Some keys have to still be identified in both keyDown and keyPress

tab for Opera.
