Fix tests "putImageData() 8" and "putImageData() 9".
Negative arguments were causing source image data to be painted wrapped-around the other side of the canvas.

Optimize Context2d::PutImageData. Benchmarked 53% faster.
Benchmark:
var canvas = new Canvas(300, 600);
var ctx = canvas.getContext("2d");
// any manipulation of canvas/ctx here.
var data = ctx.getImageData(0,0,300,600);
// time 1000x:
ctx.putImageData(data, 0, 0);

Replace CanvasPixelArray with Uint8ClampedArray to meet spec.
Added some argument testing/manipulation to match WebKit/Moz behaviors.
Additionally benchmarked:
* branching on `if (a == 0 || a == 255)`, as it is
* not branching (always doing the alpha calculation)
* Mozilla's implementation found here: https://dxr.mozilla.org/mozilla-central/source/dom/canvas/CanvasRenderingContext2D.cpp#5083
Mozilla's is insignificantly faster (p=0.17) :) so left it as-is.

Just use cairo_image_surface_create rather than cairo_surface_create_similar_image which was introduced in cairo 1.12.
Unfortunately the cairo distributed with GTK+, used in the Windows build, is only 1.10.
Using the similar_image version offers backends the chance to be more efficient, but the alternative used here is used as a fallback in the cairo code anyway.

The +1 on the offset seems to match the browser's output better, but I can't work out why it would be needed (unless it's pixel alignment related).

Add support for the lineDash API.
Described here:
http://www.w3.org/TR/2dcontext/#dom-context-2d-setlinedash
The test images match on Chrome, but not on Firefox. It looks like
Firefox resets the lineDash to [] when given invalid parameters. My
reading of the spec agrees with Chrome.
