* Surface stacking and ordering.
*
* This is handled using several linked lists of surfaces, organised into
* ‘layers’. The layers are ordered, and each of the surfaces in one layer are
* above all of the surfaces in the layer below. The set of layers is static and
* in the following order (top-most first):
* • Lock layer (only ever displayed on its own)
* • Cursor layer
* • Input panel layer
* • Fullscreen layer
* • Panel layer
* • Workspace layers
* • Background layer
*
* The list of layers may be manipulated to remove whole layers of surfaces from
* display. For example, when locking the screen, all layers except the lock
* layer are removed.
*
* A surface’s layer is modified on configuring the surface, in
* set_surface_type() (which is only called when the surface’s type change is
* _committed_). If a surface’s type changes (e.g. when making a window
* fullscreen) its layer changes too.
*
* In order to allow popup and transient surfaces to be correctly stacked above
* their parent surfaces, each surface tracks both its parent surface, and a
* linked list of its children. When a surface’s layer is updated, so are the
* layers of its children. Note that child surfaces are *not* the same as
* subsurfaces — child/parent surfaces are purely for maintaining stacking
* order.
*
* The children_link list of siblings of a surface (i.e. those surfaces which
* have the same parent) only contains weston_surfaces which have a
* shell_surface. Stacking is not implemented for non-shell_surface
* weston_surfaces. This means that the following implication does *not* hold:
* (shsurf->parent != NULL) ⇒ !wl_list_is_empty(shsurf->children_link)
