Decouple window pixmaps from scene windows One of the scene redesign goals is to make wayland surface items re-usable. So we have the same rendering path for drag-and-drop icons, software cursors, and window surfaces. The biggest issue at the moment is that window pixmaps are tightly coupled with scene windows. This change de-couples window pixmaps from scene windows. In order to achieve that, some architecture changes were made. The WindowPixmap class was replaced with the SurfacePixmap class. A surface pixmap is created by a surface item. Under the hood, a SurfacePixmap will create a PlatformSurfaceTexture object, which contains all the information necessary for the renderer. The SceneOpenGLTexture class was removed. However, the GLX and the EGL on X11 backends still mess with GLTexture's internals.

Remove scene window traces in scene items This further decouples scene items from scene windows. The SurfaceItem still needs to access the underlying window, I would like to re-iterate over that later. With this change, it will be possible to introduce WindowItem factory function in the Toplevel class.

Decouple window pixmaps from scene windows One of the scene redesign goals is to make wayland surface items re-usable. So we have the same rendering path for drag-and-drop icons, software cursors, and window surfaces. The biggest issue at the moment is that window pixmaps are tightly coupled with scene windows. This change de-couples window pixmaps from scene windows. In order to achieve that, some architecture changes were made. The WindowPixmap class was replaced with the SurfacePixmap class. A surface pixmap is created by a surface item. Under the hood, a SurfacePixmap will create a PlatformSurfaceTexture object, which contains all the information necessary for the renderer. The SceneOpenGLTexture class was removed. However, the GLX and the EGL on X11 backends still mess with GLTexture's internals.
