The user data of a wl_resource representing a wl_output protocol object used to be a pointer to weston_output. Now that weston_output is being split, wl_output more accurately refers to weston_head which is a single monitor. Change the wl_output user data to point to weston_head. weston_output_from_resource() is replaced with weston_head_from_resource(). This change is not strictly necessary, but architecturally it is the right thing to do. In the future there might appear the need to refer to a specific head of a cloned pair, for instance.

/*
|
||
* 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)
