Add an icon for a spinner with a small number of steps
The default animation of the Gtk spinner has some performance issues (see https://bugzilla.redhat.com/show_bug.cgi?id=1204242). We have found out that it helps to limit the number of steps of the animation (see https://github.com/rhinstaller/anaconda/pull/2240). However, the icon process-working-symbolic is not designed to be animated this way. When the rotation of the icon is not smooth, the spinner looks a little glitchy.
We would like to use an icon that can be animated with a very small number of steps, but still looks beautiful. Could you provide an alternative icon for a spinner, please?
