  internal package Foswiki::Plugins::TWikiCompatibilityPlugin  
 initPlugin($topic, $web, $user, $installWeb) → $boolean 
 
-  $topic- the name of the topic in the current CGI query
-  $web- the name of the web in the current CGI query
-  $user- the login name of the user
-  $installWeb- the name of the web the plugin is installed in
 earlyInitPlugin() 
If the TWiki web does not exist, change the request to the System
This may not be enough for Plugins that do have in topic preferences.
 postRenderingHandler( $text ) 
 
-  $text- the text that has just been rendered. May be modified in place.
using the same simplistic mechanism as 
DistributedServersPlugin, we find all
the System and TWiki web pub URL's and make sure they actually exist. If not,
we look in the 'other' place, and modify them if that file does exist.
 renderWikiWordHandler($linkText, $hasExplicitLinkLabel, $web, $topic) → $linkText 
 
-  $linkText- the text for the link i.e. for[[Link][blah blah]]it'sblah blah, forBlahBlahit'sBlahBlah, and for Blah Blah it'sBlah Blah.
-  $hasExplicitLinkLabel- true if the link is of the form[[Link][blah blah]](false if it's=[Blah]] or =BlahBlah)
-  $web,$topic- specify the topic being rendered
Called during rendering, this handler allows the plugin a chance to change
the rendering of labels used for links.
Return the new link text.
