[Review-3-6?] New artwork for 3.6

[Ivan Timofeev]

Hi there,

I don't know if that will affect particular builds (e.g. SUSE, RedHat 
etc) but I have pushed
cgit.freedesktop.org/libreoffice/core/commit/?id=180a67252ef9076ad5ddcc69b5dd8e1bace67913
to master and 3-6, which fixes the position of the new Start Center 
images. Just for the record. :)

Best Regards,
Ivan
