Fix GraphicsContext::roundToDevicePixels in Qt

I found the source of the problem - our GraphicsContext::roundToDevicePixels
function is wrong, as it doesn't make the right calculation in the case of
rotating images.
The attached fix makes that function completely equivalent to the CG
implementation, and rotating canvas images now look fine!
