Key to toggle fullscreen

[KenneyNL]

Add a key (F11?) to toggle between fullscreen mode.

There is one for Ubuntu I believe.

Alt+Enter is a common key binding for fullscreen, we might provide it.

Windows doesn't provide an easy and convenient way to fullscreen all applications.

[C1ffisme]

Ah Windows. Beautiful, breakable Windows.

@Calinou Alt+Enter is the keystroke used to bring CMD windows on Windows into fullscreen mode. Today most applications are using F11 for changing between fullscreen and windowed mode.

This is not very easy in Irrlicht; that's why it doesn't exist in the first place. But if someone is up to the task, go ahead.

OK

First, F11 and alt+ctrl are both commonly used in different software.

Second, I guess, no one really wants true full screen.
A simple border-less window on top of all others would be enough.
Monitor resolution change can be done regardless of the graphics engine.
So...

1. change the resolution
2. disable window borders
3. maximize the application.
   Just don't forget to restore the resolution upon exit.

That IS a hack of sorts, but who cares? (@celeron55 ?)

[Calinou]

A borderless window will slightly decrease performance, but it's perfectly acceptable today. Even Source games propose using a borderless window.

[kilbith]

If you disable the WM, you slightly increase performance at the contrary - but it's barely noticeable.

[RobertZenz]

@kilbith If disabling your WM increases performance even "barely noticeable" your machine is either way too weak or your WM is insanely broken. What you mean is most likely broken compositors, which manage to absolutely kill performance of any OpenGL application (I think Gnome managed to deliver such a broken compositor).

@4aiman The borderless window is preferable in nearly all instances, yes.

Any more comments?
Seems difficult, see c55's comment, and low priority, we already have window maximisation.

[paramat]

Author and supporter are no longer with us. Difficult. Very little gain (no border) and we can maximise already.

Very little gain (no border)
I have two toolbars, one at the top and one at the bottom of the screen. Getting rid of those would be more than a little gain to me.
