Some native platforms (mostly, X window managers) don't provide direct 
APIs to enable/disable certain window decoration buttons. A library or 
an application may provides some hints, which may or may not be 
respected by WM.

I like what we have right now, StageStyle approach. Application defines 
the purpose of the window and let the platform decide, what are 
available actions for it.
