*
* NAME
* LT_NewMenuTemplate -- Allocate and layout menu items (V11)
*
* SYNOPSIS
* Menu = LT_NewMenuTemplate(Screen,TextAttr,AmigaGlyph,CheckmarkGlyph,
* D0 A0 A1 A2 A3
*
* Error,MenuTemplate);
* D0 D1
*
* struct Menu *LT_NewMenuTemplate(struct Screen *,struct TextAttr *,
* struct Image *,struct Image *,
* LONG *,struct NewMenu *);
*
* FUNCTION
* Allocates Menus and MenuItems similar to LT_LayoutMenus().
*
* As of v18 this routine will validate menu mutual exclusion
* information.
*
* INPUTS
* Screen - Pointer to the screen the menu will appear on. This
* parameter is required and must not be omitted.
*
* TextAttr - Pointer to the TextAttr that should be used to
* layout the menus. If this parameter is omitted,
* Screen->Font will be used instead.
*
* AmigaGlyph - Pointer to the Image to use as the Amiga glyph.
* This parameter may be omitted.
*
* NOTE: Ignored by intuition.library v37 and below.
*
* CheckmarkGlyph - Pointer to the Image to use as the checkmark
* glyph. This parameter may be omitted.
*
* Error - Pointer to receive error code in case the menu
* creation or layout process fails. This parameter
* may be omitted.
*
* MenuTemplate - Pointer to a series of NewMenu structures,
* just as you would pass to
* gtlayout.library/LT_LayoutMenuA.
*
* RESULT
* Menu - Pointer to Menu structure, ready to pass to
* SetMenuStrip(), NULL on failure.
*
* NOTES
* The menu created by this function cannot be used with the
* routines LT_MenuControlTagList, LT_FindMenuCommand and
* LT_GetMenuItem.
*
* You may freely add, remove, spindle & mutilate the contents of the
* menu strip created, just don't trash or disconnect the base menu
* entry this routine creates as all menu memory tracking data is
* connected with it.
*
* SEE ALSO
* gtlayout.library/LT_DisposeMenu
* gtlayout.library/LT_LayoutMenuA
