i think that the best way to do this is an extension to wayland protocol to
indicate apps should avoid drawing frames with their toolkits. :)

this will require some negotiation before the first buffer is rendered. ie
surface created but not SHOWN... then ask wayland "given this surface, if i
showed it, should i draw frames or not?". this kind of negotiation will be
needed for many other things - like requesting what possible screen it may end
up on - or what profile to use. imagine a phone WITH a desktop monitor
attached. does the app display on the desktop monitor in "desktop mode" with
frames etc. and work with kbd+mouse, or does it display on the mobile screen
with no mouse and fill the screen etc.?
