[Libreoffice] [PATCH] Fix for Bug 37484 - On any animation change, current position in list is lost

[Luke Symes]

Hi,

Please find attached my patches to fix Bug 37484 [1]. It would be great if
someone could review them.

I ended up implementing my own method for scrolling to a listbox entry, and
also making public the methods related to absolute position of entries in
the list. I hope this was an OK thing to do? I tried hard to make the code
that saves & restores list position compact and readable; please tell me if
it makes sense. I have built and tested my changes a lot, but only on linux.

Kind regards,

Luke.
