use HAVE_STRINGS_H #include "rsvg-private.h" to get common definitions

2008-04-25  Hans Breuer  <hans@breuer.org>

	* rsvg-css.c : use HAVE_STRINGS_H
	* rsvg-path.c : #include "rsvg-private.h" to get common definitions
	* rsvg-text.c : make the text rendering capability depend on what 
	cairo provides. If there is no CAIRO_HAS_FT_FONT try to use 
	CAIRO_HAS_WIN32_FONT. Makes librsvg buildable on windows without 
	freetype dependency, bug #529889
