Bug 130668 – Implement ImageData constructors and WebWorkers exposure

• Component: Canvas
• Status: RESOLVED FIXED

[Dirk Schulze]

The spec says:

[Constructor(unsigned long sw, unsigned long sh),
 Constructor(Uint8ClampedArray data, unsigned long sw, optional unsigned long sh),
 Exposed=Window,Worker]
interface ImageData {
  readonly attribute unsigned long width;
  readonly attribute unsigned long height;
  readonly attribute Uint8ClampedArray data;
};

We should support constructors and the workers exposure.

Firefox already has this feature in the Nighlies and will ship without a flag: https://bugzilla.mozilla.org/show_bug.cgi?id=959958

Chrome has a CL for it and an Intent to ship is under way: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/FvHQUEXCgEo

The equality comparisons are false positives. Will fix indentation before landing.
