to prevent `_screen` reassign - it will be reassigned in
sendEvent: (GSAppKitWindowMoved event) after call to [self screen].
(setFrameFromString:): removed unused code because _screenForFrame:
never returns `nil`. Do not reassign `_screen` here.
send WindowDidChangeScreen notification if window was moved to other
screen.
* Source/NSScreen.m (mainScreen): returns screen of main menu if no
key window exists. With this implementation default screen (screen at
index 0 in screens array) should never be returned.
* Source/NSMenu.m (initWithTitle:): observe WindowDidBecomeKey and
WindowDidChangeScreen notifications.
(windowDidChangeScreen:): new method to handle observed notification
added above. Moves menu to screen of key window for both cases: when
key window moved to or activated on different screen.
added observer of NSApplicationDidChangeScreenParametersNotification.
(applicationDidChangeScreenParameters:): callback for added notification -
updates window position, set new screen object and saves frame if
autosave name exists.
* Source/NSScreen.m (initialize): remove observer of
NSApplicationDidChangeScreenParametersNotification - NSScreen shouldn't
do it. Backend explicitely calls -resetScreens before posting notification.
(_initWithScreenNumber:): ditto.
(_resetScreens): removed.
(deviceDescription): removed duplicated addition of NSDeviceSize object.
* Source/NSApplication.m (finishLaunching): remove observer of
NSApplicationDidChangeScreenParametersNotification.
NSApplicationDidChangeScreenParametersNotification.
(frame): use `_frame` ivar since libs-back recreates screens list.
(dealloc): remove observer.
(applicationDidChangeScreenParameters:): update _frame and _depth
ivars for bad behaving objects which retain NSScreen and not observing
screen parameters changes.
* Images/common_StepperDownHighlighted.tiff,
* Images/common_StepperUp.tiff,
* Images/common_StepperUpHighlighted.tiff: new images with arrows
similar to scroll view buttons'.
* Source/GSThemeDrawing.m (stepperUpButtonRectWithFrame:),
(stepperDownButtonRectWithFrame:): center buttons horizontally; simplify
and cleanup.
* Source/NSStepper.m (acceptsFirstResponder): return NO. Returning
YES makes sense only if `keyDown:` is implemented.
(acceptsFirstMouse:): return YES.
* Source/NSStepperCell.m (cellSize): initial implementation. Retruns
minimum size based on up and button sizes.
with separated sparated columns layout.
(tile): fix column height calculation; moved sanity check of column
height closer to calculation; removed code that duplicates code below.
