Icons created from an SVG file (such as those from an icon_set(), or
read directly with read_icon()) retain the path to their source file.
This is useful for passing icons to other packages that work with SVG
files directly, such as ggplot2 (via grid::rasterGrob() or similar) or
gt.
icon_path(x)A string (or, for an icon_vec, a character vector) giving the
path(s) to the icon's source SVG file(s) on disk.
