This section discusses all window attributes.  As mentioned earlier, a
window's attributes may be specified with either tagitems, newwindow or
extnewwindow depending on how the window is opened.

Attributes are listed here by their tagitem id name (tagitem.ti_tag).  for
each tag item, the equivalent field setting in the newwindow structure is
also listed if it exists.  Some window attributes specified with tags are
available only in Release 2 and have no NewWindow equivalent.
