Although they're in the same units, `radius` is easier to understand than `sigma` and makes the public API independent of the blur algorithm used behind the scenes. We now only keep the `sigma` terminology where the implementation is Gaussian-specific. The assumption that `sigma = radius / 2.0` is actually not new here. We just move it from `_st_create_shadow_pipeline` (gnome-shell!1905) into `clutter_blur_new`. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1908>
