This module inspects the system GTK theme, icon theme, and builds browser-compatible CSS. It is based on postcss-gtk and @jakejarrett/gtk-theme. This is alpha-quality software and a work-in-progress.
outputPath(string): The directory that the generated CSS, and the fallback CSS resides in.
If a theme is in a resource:// path, electron-gtk-theme will fallback to a file named gtk.css in a directory configured by outputPath.
