The great header file reorganization. Split up roughtly by objects.

Wed Feb  2 00:07:13 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pango-*.h: The great header file reorganization.
	Split up roughtly by objects.

	* libpango/pango-font.h libpango/fonts.h: Add generic
	font-loading and listing interfaces.

	* libpango/pangox.c: Implement font-listing/loading interfaces
	for X.

	* libpango/pango-context.[ch]: Flesh out context structure.
	Add appropriate accesors, font loading-methods, etc.

	* libpango/pango-coverage.[ch]: Coverage map objects.

	* examples/viewer.c: First stab at adding font-selection. Majorly
	deficient for the moment until we add font lists and fallbacks
	based on coverage maps.
