Introduce MetaSurfaceActor for drawing MetaWindowActor content Instead of having MetaWindowActor only have one single MetaShapedTexture as actor drawing its content, introduce a new abstract MetaSurfaceActor that takes care of drawing. This is one step in the direction to decouple MetaWaylandSurface with a MetaWindow and MetaWindowActor (except for shell/xdg surfaces) in order to finally support subsurfaces like features, or any feature where window is not drawn using a single texture. The first step, implemented in this patch, is to not have MetaWindowActor work directly with a shaped texture. There are still some cases where it simply gets the texture and goes on as before, but this should be changed by either removing the need of going via MetaWindowActor or by adding some generic interface to MetaSurfaceActor that doesn't limit its functionality to one shaped texture. There should be no visible difference nor after this patch, but meta_window_actor_get_texture() and meta_surface_actor_get_texture() should be deprecated when equivalent functionality has been introduced.

window-actor: Split into two subclasses of MetaSurfaceActor The rendering logic before was somewhat complex. We had three independent cases to take into account when doing rendering: * X11 compositor. In this case, we're a traditional X11 compositor, not a Wayland compositor. We use XCompositeNameWindowPixmap to get the backing pixmap for the window, and deal with the COMPOSITE extension messiness. In this case, meta_is_wayland_compositor() is FALSE. * Wayland clients. In this case, we're a Wayland compositor managing Wayland surfaces. The rendering for this is fairly straightforward, as Cogl handles most of the complexity with EGL and SHM buffers... Wayland clients give us the input and opaque regions through wl_surface. In this case, meta_is_wayland_compositor() is TRUE and priv->window->client_type == META_WINDOW_CLIENT_TYPE_WAYLAND. * XWayland clients. In this case, we're a Wayland compositor, like above, and XWayland hands us Wayland surfaces. XWayland handles the COMPOSITE extension messiness for us, and hands us a buffer like any other Wayland client. We have to fetch the input and opaque regions from the X11 window ourselves. In this case, meta_is_wayland_compositor() is TRUE and priv->window->client_type == META_WINDOW_CLIENT_TYPE_X11. We now split the rendering logic into two subclasses, which are: * MetaSurfaceActorX11, which handles the X11 compositor case, in that it uses XCompositeNameWindowPixmap to get the backing pixmap, and deal with all the COMPOSITE extension messiness. * MetaSurfaceActorWayland, which handles the Wayland compositor case for both native Wayland clients and XWayland clients. XWayland handles COMPOSITE for us, and handles pushing a surface over through the xf86-video-wayland DDX. Frame sync is still in MetaWindowActor, as it needs to work for both the X11 compositor and XWayland client cases. When Wayland's video display protocol lands, this will need to be significantly overhauled, as it would have to work for any wl_surface, including subsurfaces, so we would need surface-level discretion. https://bugzilla.gnome.org/show_bug.cgi?id=720631

shaped-texture: Move unobscured_region processing here We want to remove a bunch of auxilliary duties from the MetaWindowActor and MetaSurfaceActor, including some details of how culling is done. Move the unobscured region culling code to the MetaShapedTexture, which helps the actor become "more independent". https://bugzilla.gnome.org/show_bug.cgi?id=720631

surface-actor: Add setters for set_input_region / set_opaque_region Subsurfaces won't have a MetaWindow or MetaWindowActor to fetch these from, so they need to be tied directly to the MetaSurfaceActor.

Fix the input region not working properly The input region was set on the shaped texture, but the shaped texture was never picked properly, as it was never set to be reactive. Move the pick implementation and reactivity to the MetaSurfaceActor, and update the code everywhere else to expect a MetaSurfaceActor.
