	* lib/persistence.c app/load_save.c app/sheet_dialog_callbacks.c
	  lib/object_defaults.c : revert changing of Dia's XML namespace
	* lib/dia_xml.h : #define DIA_XML_NAME_SPACE_BASE with a comment
	about its purpose and relation to real world urls.

	* lib/plug-ins.h : increment DIA_PLUGIN_API_VERSION and
	added comment about when to o so
	[Should have been long time ago and probably multiple times
	to avoid crashing on older plug-ins]
	* RELEASE-PROCESS : mention DIA_PLUGIN_API_VERSION
	* plug-ins/xslt/xslt.c : use DIA_PLUGIN_CHECK_INIT

	* lib/object.c objects/UML/class.c : there are still compilers not
	supporting C99 and other GCCISMs like allocating dynamic sized arrays
	on the stack
	* objects/UML/class.h : there is a differnce between a list pointer
	and a list pointer pointer. We and GLib want the former.

	* plug-ins/pixbuf/pixbuf.c : don't use app_is_interactive () to detect
	if Gtk is initialized. Using gdk_display_get_default () avoids the
	app/* dependency and is also closer to the requirements of the
	plug-ins working.

	* plug-ins/cairo/diacairo.c : initialize "unique name" field. Also
	some #ifdefed support for Cairo backends not public available yet.

	* plug-ins/wmf/wmf.cpp : finally do extended linestyles if the
	windoze platform supports them. This should fix bug #109818, at
	least for the majority running NT or above ...
	* plug-ins/wmf/wmf_gdi.[hc] : portability stuff for the above

	* objects/makefile.msc : build Istar, Jackson and Kaos

	* objects/UML/class.c(umlclass_load) : don't wrap by default to
	keep old diagrams as they were - instead of this nice new effect ;-)
	Also make "wrap_operations" PROP_TYPE_BOOL in PropDescriptions

	* objects/UML/class.c : mark for translation _("Wrap ...

	* objects/UML/class.c : more correct types, also some default properties
	dialog pages adjustment (triggering a bug in lib/prop_widgets.c ?;)

	* objects/UML/activity.c : removed a leftover from the
	use-localization-for-font-substitution-hack

	* shapes/ChemEng shapes/Cybernetic shapes/Map/Isometric :
	'cvs admin -kb *.png' PNG files should already be *added* as binary,
	otherwise they are not readable on line-end-converting-platforms

	* plug-ins/python/use g_new0(Dia<Im|Ex>portFiler), avoids crashing
	filter_get_by_name()

	* plug-ins/python/pydia-property.c : some more g_warnings for
	not implemented conversions

	* plug-ins/python/group_props.py : ensure unique property values
	at the right place. Now something like :
	- load an old UML class diagram
	- change one of the classes to wrap operations
	- select all classes (/Select/Same Type)
	- /Dialogs/Group Properties : check wrap_operations, select '1'
	- Ok, works like a charm :-)
