/*
Bookmarks can be set with fields SET and ASK, and they can be referenced with
REF. When set, they behave like variables in writer, otherwise they behave
like normal bookmarks. We can check whether we should use a show variable
instead of a normal bookmark ref by converting to "show variable" at the end
of the document those refs which look for the content of a bookmark but whose
bookmarks were set with SET or ASK. (See SwWW8FltRefStack)
 
The other piece of the puzzle is that refs that point to the "location" of the
bookmark will in word actually point to the last location where the bookmark
was set with SET or ASK, not the actual bookmark. This is only noticeable when
a document sets the bookmark more than once. This is because word places the
true bookmark at the location of the last set, but the refs will display the
position of the first set before the ref.
 
So what we will do is
 
1) keep a list of all bookmarks that were set, any bookmark names mentioned
here that are referred by content will be converted to show variables.
 
2) create pseudo bookmarks for every position that a bookmark is set with SET
or ASK but has no existing bookmark. We can then keep a map from the original
bookmark name to the new one. As we parse the document new pseudo names will
replace the older ones, so the map always contains the bookmark of the
location that msword itself would use.
 
3) word's bookmarks are case insensitive, writers are not. So we need to
map case different versions together, regardless of whether they are
variables or not.
 
4) when a reference is (first) SET or ASK, the bookmark associated with it
is placed around the 0x14 0x15 result part of the field. We will fiddle
the placement to be the writer equivalent of directly before and after
the field, which gives the same effect and meaning, to do so we must
get any bookmarks in the field range, and begin them immediately before
the set/ask field, and end them directly afterwards. MapBookmarkVariables
returns an identifier of the bookmark attribute to close after inserting
the appropriate set/ask field.
