Test program to make sure GtkTextBuffer is in working order.

2000-06-02  Havoc Pennington  <hp@pobox.com>

        * gtk/testtextbuffer.c: Test program to make sure GtkTextBuffer
	is in working order.

	* gtk/testtext.c: Change to reflect anonymous mark API

	* gtk/gtktextview.c: Convert from mark names to GtkTextMark*.

	* gtk/gtktexttag.h (struct _GtkTextTag): remove the affects_size
	field, which was unused.

	* gtk/gtktextmarkprivate.h (GTK_IS_TEXT_MARK): add this macro,
	saves some typing.

	* gtk/gtktextbuffer.c: Switch from mark names to GtkTextMark*

	* gtk/gtktextbtree.c (gtk_text_btree_new): set the not_deleteable
	flag on the insertion point and selection bound

	Throughout, use GtkTextMark instead of GtkTextLineSegment, and
	make mark-manipulation functions take a GtkTextMark* instead of a
	mark name.

	* gtk/gtktextmarkprivate.h: Add a "not_deleteable" flag to
	GtkTextMarkBody; will be used to detect attempts to delete
	the permanent marks (insert and selection bound)
