The following revision refers to this bug:

commit 0f3eb18441ba1c98a8bb7ef8d482b22f682c6968

Create an empty interface OffScreenCanvas

This CL creates an interface OffScreenCanvas.idl according to the proposal:

At this moment, the interface only has a constructor, and its implementation is empty.

Also, a layout test is added to verify that the constructor
can be successfully called from JS, and verify the object's
width&height, together with verifying the constructor's behavior when
the argument is invalid.
