[Feature Request] Add a protocol for an always on top window (something similar to wlr-layer-shell)
One of the major problems with wayland right now is that it is practically impossible to have a window brought to the top or for a window to be always on top of other windows programatically. This leads to a crippled user experience, with nice features like picture in picture not working at all under wayland. A potential solution would be to make a new protocol that gives developers some control over window layering so that things like picture in picture and bringing windows to the top programatically is possible.
