WindowMaker Protocols and Client Messages
=========================================

_GNUSTEP_WM_MINIATURIZE_WINDOW
The _GNUSTEP_WM_MINIATURIZE_WINDOW protocol tells the WM that the
application can handle miniaturization of a window. The WM can then
send a CLientMessage of the WM_PROTOCOLS type telling the app to
miniaturize the window.

_GNUSTEP_TITLEBAR_STATE
The app can send a ClientMessage with the _GNUSTEP_TITLEBAR_STATE
message type, telling the WM which state the window is in, allowing the
WM to change the appearance of the title bar appropriately. The states are:
Key Window(0), Normal Window(1), Main Window(2). The main window is the window
the user is currently working in. The key window is the window that has
keyboard focus.

_GNUSTEP_WM_ATTR
Property for setting various attributes about the window. Can also
be sent as a Client Message for faster handling.  The structure
passed in the property request is:
  typedef struct {
    CARD32 flags;
    CARD32 window_style;
    CARD32 window_level;
    CARD32 reserved;
    Pixmap miniaturize_pixmap;		// pixmap for miniaturize button
    Pixmap close_pixmap;		// pixmap for close button
    Pixmap miniaturize_mask;		// miniaturize pixmap mask
    Pixmap close_mask;			// close pixmap mask
    CARD32 extra_flags;
  } GNUstepWMAttributes;

where flags is a set of ORed values:
WindowStyle(1<<0), WindowLevel(1<<1), MiniaturizePixmap(1<<3),
ClosePixmap(1<<4), MiniaturizeMask(1<<5), CloseMask(1<<6),
ExtraFlags(1<<7). 

If ExtraFlags is set, then extra_flags can be:
DocumentEditedFlag(1<<0), WindowWillResizeNotificationsFlag(1<<1),
WindowWillMoveNotificationsFlag(1<<2), NoApplicationIconFlag(1<<5),
WMFHideOtherApplications(10), WMFHideApplication(12)

Window Style can be an ORed value consiting of any one or more of
NSBorderlessWindowMask(0), NSTitledWindowMask(1),
NSClosableWindowMask(2), NSMiniaturizableWindowMask(4),
NSResizableWindowMask(8), NSIconWindowMask(64) NSMiniWindowMask(128).

Window Level can be one of NSDesktopWindowLevel(-1000),
NSNormalWindowLevel(0), NSFloatingWindowLevel(3),
NSSubmenuWindowLevel(3), NSTornOffMenuWindowLevel(3),
NSMainMenuWindowLevel(20), NSStatusWindowLevel(21),
NSModalPanelWindowLevel(100), NSPopUpMenuWindowLevel(101),
NSScreenSaverWindowLevel(1000).
