Disabling JavaFX minimise/maximise/etc buttons

[Anthony Petrov]

Hi Artem,

Do you propose to add another StageStyle - namely, a DIALOG? Note that 
styles cannot be combined in a mask, meaning that developers won't be 
able to create e.g. transparent dialogs, or utility dialogs.

Generally, I like the idea of defining the purpose of a window and 
letting the OS/GUI toolkit decide what works best for it, but I'm not 
sure if we can apply it for this particular use case. Also, I think that 
ability to disable maximization/minimization of a window might be useful 
for purposes other than just displaying dialogs.

BTW, isn't the setResizable(false) a good approximation for our 
requirements? You can still minimize such a window, but I think this is 
reasonable. E.g. OS X will minimize both the dialog and its owner 
window, allowing a user to perform other tasks unrelated to the dialog 
and windows it blocks. Why do we want to disable minimization?

Anthony
