Icon with a PANDA eating some bamboo by a Pond

These are icons created by @skreetskrat based upon a suggestions by @ioerror to include bamboo because "bamboo telegraph" in Chinese means "hearsay" or "back alley news".  

I renamed the original icons in a7ed942 by @skreetskrat to *-suqare.* when I made her blue background into an imho more pond-like amorphous blob.

As I understand it, these .svg icons should work as is on Ubuntu, but if not, or if you're looking into another platform, then I listed some conversion tools in https://github.com/burdges/pond/commit/18cdb4e86666ec7c22eba2c5068ed48dc2ec4b4f.

As an aside, the original Adobe Illustrator .ai file added by @skreetskrat in 15b08fa7 is 1.2M, while the .svg files are only 130k each, so maybe @agl should drop 15b08fa7 before pulling into master.
