Copyright Licence Statement

[Jonathan Riddell]

I've submitted a patch to add a Breeze icon theme to LibreOffice for use with KDE Plasma 5.

All of my past & future contributions to LibreOffice may be licensed
under the MPLv2/LGPLv3+ dual license.

The icons themselves are GPL2+.  The Tango icons are CC-BY-SA 3.0 and
Oxygen icons are LGPL 3+.  What is the preferred licence for icons in
LibreOffice?  I expect the artist will agree.
