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
