The xdg_toplevel capabilities are meant to let the compositor know what configurations a client can be configured to. This is meant to make it possible to disallow a compositor to maximize, fullscreen etc a surface, which would otherwise mandate the client to configure the surface according to dimension in the xdg_toplevel.configure event.
This makes it possible to create non-resizable surfaces as well as surfaces with only a certain aspect ratio allowed, by making them un-fullscreen:able and un-maximize:able. Signed-off-by: Jonas Ådahl <jad...@gmail.com> --- This is an alternative solution to the s/must/should/ patch. I made a separate enum, because certain state enum entries make no sense to support or not, since they don't mandate anything (resize, activated so far).
