Implemented now on OS X, where I've also implemented the RESIZABLE flag (untested).
It's a bit unstable though, the application doesn't seem to behave properly when the frame is toggled (it becomes unresponsive and I get error messages on terminal).
It seems best to simply set the flag when the window is created and leave it at that.

By the way - I just realised that "al_toggle_display_flag" is a misnomer, since you're not toggling the flag but setting it to a well-defined value.

Do you mean in general, or a fake fullscreen mode that covers the display area?
Toggling to a fullscreen mode is (again) not trivial, certainly not on OS X. Resizing the window to cover the entire screen at the desktop resolution is easy (at least on 10.5+, it may be impossible on older versions without actually creating a new window) but the reverse is not.
Anyway, since that's basically a resize operation, I would prefer it to be handled as a resize operation, not a display flag.
