Thorsten Behrens 09b546cf9c Fix overloaded-virtual warning in canvas
With enabled -Woverloaded-virtual gcc warning (see
http://lists.freedesktop.org/archives/libreoffice/2011-March/009567.html),
canvas exposed a nasty clash between WeakComponentImplHelper::disposing
and XEventListener::disposing. Fixed by overriding *once* in baseclass,
and then calling disambiguated, renamed methods.
