  [cairo] ASSERTION FAILED: destSize > 0 in WebCore::Cairo::calculateSubsurfaceRect
https://bugs.webkit.org/show_bug.cgi?id=279649

Reviewed by Don Olmstead.

WebCore::Cairo::calculateSubsurfaceRect wrongly assumed destSize and
srcSize were always positive. Some canvas tests caused an assertion
failure in it. They can be negative.
