Widget catalog: icons for survival analysis do not render properly

[JakaKokosar]

Widget icons in Orange look OK, but they somehow do not render properly on the webs.

@markotoplak, if I am not mistaken, you once mentioned that icons are broken when using Orange on Linux, right? I guess there must be something wrong with these particular icons because others seem to be OK.

@ajdapretnar, do you have any ideas?

Wow, that'a new one. Could it be something related to layers in SVG?
