move pango_shape and pango_reorder_items in here.

2000-12-15  Havoc Pennington  <hp@pobox.com>

* pango/pango-glyph.h: move pango_shape and pango_reorder_items in
here.

* pango/pango-break.h: move most of pango.h in here, so that
pango.h can be the only file that includes pango-enum-types.h, so
that changing any header doesn't end up rebuilding all of pango
due to a rebuild of pango-enum-types.h.

* pango/makeenums.pl: script to generate pango-enum-types.[hc]

* pango/Makefile.am (pango_headers): built pango-enum-types.h,
pango-enum-types.c that do enum type registration; add
pango-break.h; do some assorted rearranging to handle the
built headers

* pango/pango.h: moved most of it to pango-break.h

* pango/break.c: include individual headers, not pango.h

* pango/shape.c: ditto

* pango/reorder-items.c: ditto

* pango/querymodules.c: ditto

* pango/pango-layout.c: ditto

* pango/pango-indic.c: ditto

* pango/mapping.c: ditto

* pango/itemize.c: ditto

* pango/fonts.c: ditto
