Patch flips around the logic so we don't touch m_context3d or m_drawingBuffer if there's no drawingContext(), which makes sense since if there is no drawingBuffer() we won't be doing any software draws either.  This also means that <canvas> elements that are zero sized or excessively large will not get composited layers since canvas layers are only set if CanvasRenderingContext2D::isAccelerated() is true which checks m_context3d.
