How can we test this? :)

[juliushaertl]

@skjnldsv You need imagemagick enabled in your webserver setup. Then the endpoint http://localhost/index.php/apps/theming/favicon/core should return an ico file with different sizes.

I did, but I only get one picture. 32x32

[juliushaertl]

@skjnldsv I think most browsers/image viewers will show only a single image. Opening in gimp should show up the different sizes as single layers.

[skjnldsv]

Hum, I only have one layer. Header is set and working.

[juliushaertl]

Can you change the color and try it again? I guess we need to trigger the regeneration when updating.

[skjnldsv]

Perfect!

I like it and it works here, but somehow postgres fails hard:

@MorrisJobke Tests run fine locally. I rebased and pushed again. Let's see if that one still fails.
