How to create a new variant of this theme:

1) edit svg files

2) use roundsvgopacity3.sh on edited svg files

3) use make_theme.sh to change colors and alpha values with regex and make the
   svg files color-scheme-aware (see alpha.txt and colors.txt for the values to
   replace)

Note: The resulting theme will use the colors from the color scheme set in
system settings, unless there is a 'colors' file present in the theme
directory, in which case those colors will be used instead.
