it requires this one first:

http://cgit.freedesktop.org/libreoffice/core/commit/?id=1024c172a5bfb3d85a86fcf7a046aa2b03950edd

but then i still got a trivial conflict, so i've merged the 2 commits
into one that applies on top of the above, see attachment.

because the types of the elements are different, the return value has
uno::Reference of XFooPrimitive while the member is changed to contain
rtl::Reference of BorderLinePrimitive so it's not necessary to
dynamic_cast while iterating over it.
