Demo content about gallery

For me it’s especially important that the Gallery app nicely handles:

• SVG files
• small icons, not upscaling them in an ugly fashion but still making them visible
• images with transparency, be it PNG or SVG – especially black ones. Wikipedia handles this very nicely without a switcher: owncloud/gallery#226

Test files for black transparent PNG https://github.com/opensourcedesign/opensourcedesign.github.io/blob/master/images/foss-logo-512.png and SVG https://github.com/opensourcedesign/opensourcedesign.github.io/blob/master/images/foss-logo-512.svg

SVG files are disabled by default for security reasons, but if enabled, browsers do an OK job, as long as there isn't too much transparency.

Small icons are a tough one. You can't have a photowall made of 50x50 GIFs, so there has to be some scaling, but the admin decides how much.

@jancborchardt I think your list should be converted into acceptance tests so that we can work on each individual case if it doesn't match your expectations.

We should still try to come up with as much content as possible and offer a download so that people can use that to quickly test PRs, etc.
