These boolean window tags are alternatives to the newwindow.flags bit
fields with similar names.  Unlike the tags discussed above, the ti_Data
field of these tagitems is set to either true or false.

WA_SizeGadget
    Specifying this flag tells Intuition to add a sizing gadget to the
    window.  Intuition places the sizing gadget in the lower right corner
    of the window.  By default, the right border is adjusted to
    accommodate the sizing gadget, but the application can specify one of
    the following two flags to change this behavior.  The WFLG_SIZEBRIGHT
    flag puts the sizing gadget in the right border.  The
    WFLG_SIZEBBOTTOM flag puts the sizing gadget in the bottom border.
    Both flags may be specified, placing the gadget in both borders.
    Equivalent to newwindow.flags wflg_sizegadget.

WA_SizeBRight
    Place the size gadget in the right border.  Equivalent to
    newwindow.flags wflg_sizebright.

WA_SizeBBottom
    Place the size gadget in the bottom border.  Equivalent to
    newwindow.flags wflg_sizebbottom.

WA_DragBar
    This flag turns the entire title bar of the window into a drag
    gadget, allowing the user to position the window by clicking in the
    title bar and dragging the mouse.  Equivalent to newwindow.flags
    WFLG_DRAGBAR.

WA_DepthGadget
    Setting this flag adds a depth gadget to the window.  This allows the
    user to change the window's depth arrangement with respect to other
    windows on the screen.  Intuition places the depth gadget in the
    upper right corner of the window.  Equivalent to newwindow.flags
    WFLG_DEPTHGADGET.

WA_CloseGadget
    Setting this flag attaches a close gadget to the window.  When the
    user selects this gadget, Intuition transmits a message to the
    application.  It is up to the application to close the window with a
    closewindow() call. intuition places the close gadget in the upper
    left corner of the window. Equivalent to newwindow.flags
    WFLG_CLOSEGADGET.

WA_ReportMouse
    Send mouse movement events to the window as x,y coordinates.  Also
    see the description of the IDCMP flag idcmp_mousemove, in the chapter
    "Intuition Input and Output Methods."  Equivalent to newwindow.flags
    WFLG_REPORTMOUSE.

    The WFLG_REPORTMOUSE flag in the Flags field of the window structure
    may be modified on the fly  by the program.  Changing this flag must
    be done as an atomic operation.  Most compilers generate atomic code
    for operations such as window->flags |= WFLG_REPORTMOUSE or
    window->flags &= ~WFLG_REPORTMOUSE.  If you are unsure of getting an
    atomic operation from your compiler, you may wish to do this
    operation in assembler, or bracket the code with a forbid()/permit()
    pair.

    The use of the reportmouse() function is strongly discouraged, due to
    historic confusion over the parameter ordering.

WA_NoCareRefresh
    This window does not want idcmp_refreshwindow events.  set this flag
    to prevent the window from receiving refresh window messages.
    Equivalent to newwindow.flags wflg_nocarerefresh.  intuition will
    manage beginrefresh() and endrefresh() internally.

WA_Borderless
    Open a window with no borders rendered by Intuition.  Equivalent to
    newwindow.flags wflg_borderless.

    Use caution setting this flag, as it may cause visual confusion on
    the screen.  Also, some borders may be rendered if any of the system
    gadgets are requested, if text is supplied for the window's title
    bar, or if any of application gadgets are in the borders.

WA_Backdrop
    Make this window a backdrop window.  equivalent to newwindow.flags
    WFLG_BACKDROP.

WA_GimmeZeroZero
    Set this tag to create a gimmezerozero window. gimmezerozero windows
    have the window border and border gadgets rendered into an extra
    layer. This extra layer slows down window operations, thus it is
    recommended that applications only use GimmeZeroZero windows when
    they are required. For clipping graphics to the area within the
    borders of a window, see the discussion of "regions" in the "layers
    Library" chapter. Equivalent to newwindow.flags wflg_gimmezerozero.

WA_Activate
    Activate the window when it opens.  Equivalent to newwindow.flags
    WFLG_ACTIVATE.  Use this flag carefully, as it can change where the
    user's input is going.

WA_RMBTrap
    Catch right mouse button events for application use.  Set this flag
    to disable menu operations for the window.  When set, right mouse
    button events will be received as idcmp_mousebuttons with the menuup
    and MENUDOWN qualifiers.  Equivalent to newwindow.flags wflg_rmbtrap.

    The WFLG_RMBTRAP flag in the window structure flags field may be
    modified on the fly by the program.  Changing this flag must be done
    as an atomic operation, as Intuition can preempt a multistep set or
    clear operation.  An atomic operation can be done in assembler, using
    68000 instructions that operate directly on memory.  If you are
    unsure of generating such an instruction, place the operation within
    a forbid()/permit() pair.  this will ensure proper operation by
    disabling multitasking while the flag is being changed.

WA_SimpleRefresh
    The application program takes complete responsibility for updating
    the window.  Only specify if TRUE.  Equivalent to newwindow.flags
    WFLG_SIMPLE_REFRESH.

WA_SmartRefresh
    Intuition handles all window updating, except for parts of the window
    revealed when the window is sized larger.  Only specify if TRUE.
    Equivalent to newwindow.flags wflg_smart_refresh.

    WA_SmartRefresh windows without a sizing gadget will never receive
    refresh events due to the user sizing the window.  However, if the
    application sizes the window through a call like changewindowbox(),
    zipwindow() or sizewindow(), a refresh event may be generated.  use
    WA_NoCareRefresh to disable refresh events.

WA_SuperBitMap
    This is a pointer to a bitmap structure for a superbitmap window. the
    application will be allocating and maintaining its own bitmap.
    Equivalent to newwindow.bitmap.  setting this tag implies the
    WFLG_SUPER_BITMAP property.

    For complete information about SuperBitMap, see
    "setting up a superbitmap window" in this chapter.

WA_AutoAdjust
    Allow Intuition to change the window's position and dimensions in
    order to fit it on screen.  The window's position is adjusted first,
    then the size.  This property may be especially important when using
    wa_innerwidth and wa_innerheight as border size depends on a user
    specified font.

WA_MenuHelp (new for V37, ignored by V36)
    Enables idcmp_menuhelp: pressing help during menus will return
    IDCMP_MENUHELP message.  See the "intuition menus" chapter for more
    information.

WA_Flags
    Multiple initialization of window flags, equivalent to
    newwindow.flags. use the wflg_ constants to initialize this field,
    multiple bits may be set by ORing the values together.

WA_BackFill
    Allows you to specify a backfill hook for your window's layer.  See
    the description of createupfronthooklayer() in the "includes and
    Autodocs" manual.  Note that this tag is implemented in V37, contrary
    to what some versions of the include files may say.
