[Libreoffice-ux-advise] Remove outdated Gallery images

Hi,

I created a patch that removes the outdated Gallery images: 
https://gerrit.libreoffice.org/4993
Now there were some objections because of breaking old documents (when 
people have linked content from the gallery into their documents).
Also I removed the bullets which are used in the "Bullets and Numbering" 
dialog.

You can some opinions on the thread on the Dev list here: 
http://nabble.documentfoundation.org/Comment-on-patch-quot-Remove-old-outdated-gallery-images-and-sounds-quot-td4066477.html

Now the questions are:
- Is it ok to break old documents by removing these images from the 
galleries?
- Do we also want to remove the sounds?
- Do we also want to remove the whole "Graphical bullets" feature?

Please share your thoughts.

Thanks
Samuel
