don't create dangling pointers to the appearance attributes from the line

2000-11-30  Havoc Pennington  <hp@pobox.com>

* gtk/gtktextdisplay.c (gtk_text_layout_draw): don't create
dangling pointers to the appearance attributes from the
line display

* gdk/gdkdraw.c (gdk_drawable_get_image): allow negative
width/height to mean "full width/height of drawable"

* gtk/gtktextview.h, gtk/gtktextview.c: Implement double/triple
click to select word/line

* gtk/gtktextiter.c (test_log_attrs): include paragraph delimiters
when getting log attrs. Get a slice, so that pixmaps and stuff
are properly handled.

* gtk/gtktextbuffer.c (paste): Fix pasting to work properly if you
paste into the selection (replaces selection now, previously
crashed or added to selection). Reveals longstanding btree bug -
select multiple lines, middle-click on the selection, boom. This
isn't related to my changes though.

* gtk/gtkentry.c (gtk_entry_move_forward_word): Update to reflect
PangoLogAttrs changes
(gtk_entry_move_backward_word): ditto

        * gtk/gtktextlayout.h, gtk/gtktextlayout.c: Make the iter motion
	functions return bool whether the iter moved onto a
	dereferenceable position.

	 * gtk/gtktextview.h, gtk/gtktextview.c: Add a bunch of public
	 functions for motion in terms of display lines.

	 * gtk/gtktextmark.c (gtk_text_mark_get_buffer): Add function to
	 get the buffer a mark is inside
