Memory management functions for PangoItem.

Mon Mar 13 10:54:48 2000  Owen Taylor  <otaylor@redhat.com>

	* pango/pango-item.[ch]: Memory management functions for PangoItem.

	* pango/*.[ch]: Random constification.

	* pango/pangox.c pango/pango-layout.c pango/pango-context.c:
	Add an extra_attrs field to PangoItem. Use this to handle underlining
	for PangoLayout.

	* examples/viewer.c (reload_font): Make paragraphs global
	to save the complexity of passing it around all over the place.

	* pango/pango-layout.[ch] (pango_layout_context_changed): Add
	a function to reset the layout on changes to the layout's
	context.

	* pango/pangox.c (pango_x_make_matching_xlfd): Prefer bitmap
	to scaleable if the discrepancy is < 1 pixel. (Probably not
	the ideal criterion.)

	* pango/pangox.c (pango_x_font_map_for_display): Fix resolution
	computation error.

	* pango/pango-layout.c (pango_layout_check_lines): Handle
	text with embedded newlines.

	* pango/pangox.c (pango_x_render_layout): Fix y to refer
	to the top of the layout, not the baseline of the first
	line.

	* pango/pango-layout.c (process_item): Don't wrap if width is
	set to -1.

	* Makefile.am configure.in **/*.[ch]: move libpango/ directory
	and fix all headers to install under include/pango/
