	* doc/sheet.dtd doc/diagram.dtd : the namespace does *not*
	match the website anymore, i.e. sould remain unchanged.
	See below and lib/dia_xml.h for the reasoning

	* lib/libdia.def : removed dia_color_selector_get_type

	* lib/dia_image.c(dia_image_load) : check for pixbuf warnings
	(like broken PNG) and g_warning if appropriate

	* app/interface.c : #include "message.h"

	* app/diaunitspinner.hc : replaced the superfluous #if-0-juggling,
	used #error "Moved to lib/widgets.[hc]" instead (IMO it would be
	better to just move diaunitspinner to lib/ instead of polluting
	widgets.[hc] even more ;)
	* app/makefile.msc lib/libdia.def : updated

	* app/filedlg.c : patch from gtk@roboros.com, fixes #156224
	* app/app_procs.c : patch from gtk@roboros.com, fixes #156088

	* config.h.win32 : #define HAVE_CAIRO to let the Cairo plug-in
	do something useful when compiled

	* plug-ins/cairo/diacairo.c : added 'PNG with alpha' rendering.
	Also some more #ifdefed backends usage.
