Use
This service is issued whenever SWI DrawFile_DeclareFonts encounters an object whose type it doesn’t know.
Notes
Extension modules should recognise the object type, declare the fonts in it and then claim the service. Errors should only be reported if there is no error presently known – the Drawfile DrawFile module will continue after errors, but only report the first one.
