  Requirements:
  
- * the implementation must be completely editor-agnostic
+  * the implementation must be completely editor-agnostic
- * some editors have very good link/image editing
facilities (to set title, class, target, size etc.), others
are very rustic. the generic usecases should be able to
provide all those features, but they must be switchable in
case an editor wants to use its own facilities.

  Idea: provide the new usecase window with a
linkData/imageData object containing default settings (see
below), and only display form fields for those attributes
that are (!undefined) in linkData/imageData.
  
+ Problem: passing data by creating an attribute in the new
window object does not work reliably in Firefox if the
window already exists:
+ {{{
+   var foo =
window.open("someurl","WindowName",
"someoption=no...");
+   foo.lenyaLinkData = {....};
+ }}}
+ 
+ It seems like the window nukes the field again after it
has been set :( resetting at a later time works, though. not
nice.
+ 
+ Solution: provide a callback that the child window can
call.... let's see how it works out.
   
+ 
  Each editor module can access and use the generic
insertImage and insertLink implementations in the editors
module. The most common way to do that is to use a
javascript window.open call to create a separate window for
the usecase:
  {{{
    <img src="linkbutton.gif"
onclick="window.open('?lenya.usecase=editors.insertLink
&lenya.editorModule=$YOUREDITOR')" /><br
/>
