Reviewed by Tim Nguyen.

The commit in 263694 at main caused a regression when calculating the dirty region
of a putImageDataUpdate. It accidentally removed a reference marker on a parameter.

* Source/WebCore/html/canvas/CanvasRenderingContext2DBase.cpp:
(WebCore::computeImageDataRect): Make sure the destRect parameter is a reference because it is updated.
(WebCore::CanvasRenderingContext2DBase::putImageData): Leave a fixme!
