Re: [AD] Resizable windows on Mac OS X

["Peter Hull" <peterhull90@xxxxxxxxxx>]

Actually you don't need to keep willResize:toSize: because there's a
setMinSize: for windows. Patch attached, see what you think. I
enforced it for manual setting via al_resize_display too, dunno if
this is right or not.
