This came up before. It looks like it does have to be flags. The shell 
is interested in knowing what state it would be in if minimized or 
fullscreen is turned off, otherwise it cannot implement a "turn off 
fullscreen" button. I think however it does not have to be any more 
complex than flags, there can be precedence rules:

   Minimized means ignore maximize/fullscreen
   Fullscreen means ignore maximize
