Image resources should be added to the components/resources/default_%d_percent
directories (you'll need 100%, 200%, and 300% versions of the icon). You should
also create components/resources/physical_web_ui_scaled_resources.grdp and
define the resource ID there. Add the new .grdp file to
components/resources/components_scaled_resources.grd

See
https://cs.corp.google.com/clankium/src/components/resources/flags_ui_scaled_...
for an example.

If you haven't already, run tools/resources/optimize_png_files.sh on the new
image resources. If they were already in Chrome they may already be optimized,
but it doesn't hurt to run it again.
