In the _all_ installer we have slightly over 100 LibreOffice UI
languages. The code in the custom action that de-selects UI languages
based on the Windows UI language(s) and the user's locale had a limit
of 100.

The consequence was that a few of the alphabetically last LibreOffice
UI languages: Ukrainan, Urdu, Uzbek, Venda and Xhosa, were not
de-selected even if none of those languages was used by the user or
Windows, and thus got installed in a "quick" install and also in a
"custom" install unless the person running the installer noticed.

Reported by aseques_ on IRC, no bug filed yet.

The header/footer objects are cunning wrappers to pretend to some parts
of the drawing stuff that there are multiple objects, while in reality
there is only one. So call HasText actually gets a totally different
object from the cast :-(
