docs: sphinx/kfigure.py: Delegate inkscape msg to kernellog.verbose
Depending on its version, distro config, and system-setup type, inkscape(1) emits various warning messages which are harmless in command-line uses. List of such warning messages (incomplete, long ones wrapped): - Gtk-Message: hh:mm:ss.nnn: Failed to load module "canberra-gtk-module" - Unable to init server: Could not connect: Connection refused - Failed to get connection - ** (inkscape:xxx): CRITICAL **: hh:mm:ss.nnn: dbus_g_proxy_new_for_name: assertion 'connection != NULL' failed - ** (inkscape:xxx): CRITICAL **: hh:mm:ss.nnn: dbus_g_proxy_call: assertion 'DBUS_IS_G_PROXY (proxy)' failed - ** (inkscape:xxx): CRITICAL **: hh:mm:ss.nnn: dbus_g_connection_register_g_object: assertion 'connection != NULL' failed - ** (inkscape:xxx): WARNING **: hh:mm:ss.nnn: Fonts dir '/usr/share/inkscape/fonts' does not exist and will be ignored. To avoid unnecessary anxiety, capture the message and output it via kernellog.verbose or kernellog.warn depending on the exit code.
