Re: LYNX-DEV USEMAP problems (was Re: fotemods.zip update)

[Klaus Weide]

That USEMAP stuff sure isn't easy to understand, and I am still trying
to understand what the FOTEMODS description exactly means :)
I haven't looked at the code changes yet, may have other comments later.
For now just one related thing:

It seems the ImageMap structured never get deleted (except at program
exit), and there is now way to "uncache" them.  This means that if
a map changes during the lifetime of a Lynx session (and the document
is reloaded), old (deleted) AREA entries will continue to show up.
I think this cold simply be improved if LYAddImageMap() would just
delete an ImageMap if it finds there already is one with the same 
address, and then create a new (empty) one, instead of reusing what
it finds.

Right - but that is not what my patch did.  The

    if (!LYMapsOnly || me->text)
        UPDATE_STYLE;

would do UPDATE_STYLE even in the LYMapsOnly==TRUE case, if for some
reason there *was* a me->text -- which normally should not happen.
Just a precaution...
