When grabbing the window we have to clip the window using the root item size. Depending on the window manager the window is resized. Another issue is that when grabbing the window offscreen the pixel ratio is always 1. Before we assumed that the pixel ratio of all images is the same for the host process as for the puppet. This is not necessarily anymore and we have to set and forward the correct pixel ratio. Change-Id: I36b467291ab120f825119adea4ed7db10d34266d Reviewed-by: Miikka Heikkinen <miikka.heikkinen@qt.io>
