Streams components and their properties in inherited forms.
procedure WriteDescendentRes(const ResName: string; Instance, Ancestor: TComponent);
Do not call WriteDescendentRes directly. WriteDescendentRes is called automatically by WriteComponentRes.
WriteDescendentRes writes a standard Windows resource-file header to the stream, using the resource name passed in ResName as the name of the resource. It then calls WriteDescendent to write Instance to the stream as a descendant of Ancestor.
