Comment 1 for bug 1388382

There is a legacy reason for this. Variety was initially in Ubuntu Software Center, where the requirement was that all application files, except for the desktop file should be within the app directory in /opt/extras.ubuntu.com/variety/. This included icons.
Variety still uses the same build process and same conventions and installs in opt.

I am in the process of changing this, and Variety will sometime soon be packaged in the ordinary Debian way. When this happens I will also package the icons the usual way and name them simply "variety" and "variety-indicator".

I'm not still sure what I should do with the indicator icon customization options in Preferences -> Customize. Currently one can change the indicator icon from the program. Once the icons are themable, this might be superfluous, but on the other hand, most themes won't have dedicated icons for Variety's indicator so I guess it makes sense to leave the "light" and "dark" options. So we might end up with "variety-indicator-light" and "variety-indicator-dark".
