Fix AJAX error reporting on IE8

baa3559df1 Graceful handling of cross-domain tilesource failures on IE<10
The TileSource error handling path used to raise non-obvious
"Unspecified error" exceptions on IE < 10 when configured with a URL
from a different origin (hostname or port) because the handler included
``xhr.status`` in the error message, triggering a security exception.

Now the second exception is caught and the log message will use the
original exception message instead to make the root cause more obvious.

1b6cf93474 Graceful handling of IE cross-domain AJAX failures
Prior to IE 10, XmlHttpRequest cannot be used for requests to a
different origin even when the target URL's CORS headers would allow
access (see http://caniuse.com/#feat=cors).

This is easy to miss in testing if you use a single origin during
testing but have a CDN or domain-sharding for production and will break
the error handler function passed to makeAjaxRequest() if that code
assumes it can access properties on the request object.

This adds a more informative pointer to Microsoft's documentation when a
security exception is raised.

0bb9c5be97 issue:
canvas pans when tap on touch screen

reason:
    onTouchStart calls onMouseDown which registers 'mousemove' event handler.
    when I tap on touch screen, even though browser did not dispatch 'touchmove' event, it dispatched 'mousemove' event.
    therefore, the 'mousemove' handler pans canvas.

fix:
    stop onTouchStart handler registering 'mousemove' handler as onMouseMove will be properly triggered by onTouchMove

f2cba16a8b Safe cleanup in makeAjaxRequest error handler

643ee211ca Remove unused variables
Mostly unused function arguments but there were also a fair number
of legacy names which are now no longer used.

One question which comes up – mostly in tilesource.js – is whether
there is any value in leaving unused variables for functions which
are intended to be overridden anyway. I'm inclined to say that the
docs + tests need to be sufficient as there's no enforcement that
whatever is in the base implementation will actually be followed by
any of the real functions.

b754ea834f Merge pull request #112 from openseadragon/blur
Fixed blendTile()-related blurriness issue (for #95)

Ventero
b66dd7bed0 Don't load the tile source again when creating a navigator.
Previously, when showNavigator was set to true when creating the
viewer, the navigator would unnecessarily load and parse the tile
source, even though a fully parsed object already exists.

1d51b72785 Fixed blendTile()-related blurriness issue
We were setting drawer.updateAgain to the result of each blendTile(),
which meant it was keeping only the last result. Instead we should have
been only setting it to true if blendTile returned true, but never
setting it to false. Fixed.

568d6a1c6b Paranoid requestAnimationFrame for antique Firefox
Very old versions of Firefox - e.g. Firefox 7 - have
window.requestAnimationFrame but not cancelAnimationFrame. This is a
very old release so the easiest fix is simply to check for both of the
functions which we intend to call and fall back on traditional behaviour
if both aren't present.

Drawer tries to emit events on the parent Viewer object but doesn't have
a reference to it.  Add a reference when constructing the Drawer.
