	* gdk-pixbuf/gdk-pixbuf-private.h
	* gdk-pixbuf/gdk-pixbuf.c
	* gdk-pixbuf/gdk-pixbuf.h
	* gdk-pixbuf/io-jpeg.c
	* gdk-pixbuf/io-png.c: changed GDK_PIXBUF_ERROR_BAD_OPTION_VALUE to
	GDK_PIXBUF_ERROR_BAD_OPTION to we can use it for bad keys too. Added
	new public API gdk_pixbuf_get_option() to retrieve key/value pairs
	set by an image loader. Added support for saving and reading PNG tEXt
	chunks in PNG images.

	* demos/testpixbuf-save.c
	* demos/testpixbuf-scale.c: simple tests for the new PNG tEXt chunk
	feature.

	* gdk-pixbuf/tmpl/gdk-pixbuf.sgml: adapt to changes in GDK_PIXBUF_ERROR
	enum.
