Drawing an SVG image into a <canvas> that is not in the DOM draws the wrong region

Source/WebCore:
In the event where the <img> element that we are passing to CanvasRenderingContext2D.drawImage()
points to an SVG resource, we ensure that the container for the SVG image is sized to match the
HTML element. The necessity for setting this container size, explained in webkit.org/b/148845,
is that we must ensure a cached image does not have an outdated container size.

LayoutTests:
Adding a series of new tests to check we correctly respect mismatching source and
destination rectangles with SVG images as sources, both with the source <img> element
being present and absent from the DOM, and explicit sizes being set or not set.
