* app/load_save.c : adjust the connections positions automatically,
	it is impossible to do so while generating
	* lib/element.h lib/object.h lib/orth_conn.h lib/properties.h
	  objects/UML/generalization.c : marked more properties optional - if
	they are properly initialized - to get rid of a lot of g_warnings()
	and one step further to fix #56233
	* samples/gobj-parse.c : a simple parser to generate a class diagram
	out of GObject using headers to test the above
