Pop!_OS inspired spinner theme for plymouth.
The spinner icon was taken from /usr/share/icons/Pop/scalable/status/process-working-symbolic.svg and the color changed to white.
The original icon can be found here.
I also added a script which uses Inkscape in order to generate the animation frames from the SVG directly.
./make-frames.sh <output_file_name>
The script will automatically look for root.svg and use that as the base.
I made it so the script will create a full rotation animation in 60 frames.
