struct ssd_part and struct node_descriptor seem to have essentially the same purpose: tag a wlr_scene_node with some extra data indicating what we're using it for. Also, as with enum ssd_part_type (now lab_node_type), ssd_part is used for several types of nodes that are not part of SSD. So instead of the current chaining (node_descriptor -> ssd_part), let's flatten/unify the two structs. In detail: - First, merge node_descriptor_type into lab_node_type. - Add a separate view pointer in node_descriptor, since in the case of SSD buttons we need separate view and button data pointers. - Rename ssd_part_button to simply ssd_button. It no longer contains an ssd_part as base. - Add node_try_ssd_button_from_node() which replaces node_ssd_part_from_node() + button_try_from_ssd_part(). - Factor out ssd_button_free() to be called in node descriptor destroy. - Finally, get_cursor_context() needs a little reorganization to handle the unified structs. Overall, this simplifies the code a bit, and in my opinion makes it easier to understand. No functional change intended.
