/**
* wlr_layer_shell allows clients to arrange themselves in "layers" on the
* desktop in accordance with the wlr-layer-shell protocol. When a client is
* added, the new_surface signal will be raised and passed a reference to our
* wlr_layer_surface. At this time, the client will have configured the surface
* as it desires, including information like desired anchors and margins. The
* compositor should use this information to decide how to arrange the layer
* on-screen, then determine the dimensions of the layer and call
* wlr_layer_surface_configure. The client will then attach a buffer and commit
* the surface, at which point the wlr_layer_surface map signal is raised and
* the compositor should begin rendering the surface.
