So far updating the cursor image was not really defined. It was possible to use the cursor image from the wayland seat or have a custom set cursor image. But there are no rules in place to decide which one to use when. With this change a dedicated CursorImage class is introduced which tracks the cursor image changes on the seat, on the decoration, in the effects and so on. In addition it tracks which is the current source for the image, that is whether e.g. the cursor from the seat or from effects override should be used. Whenever the cursor image changes a signal is emitted, which is connected to the signal in AbstractBackend. Based on that the backends can directly show the image. The existing code in the backends to install a cursor shape or to install the cursor from the server is completely dropped. For the backend it's irrelevant from where the image comes from. A new feature added is that the cursor image is marked as rendered. This is then passed on to the frame rendered in the Surface and thus animated cursors are finally working. Unfortunately animated cursors are broken in Qt (see https://bugreports.qt.io/browse/QTBUG-48181 ).
