Make PangoEngine{,Lang,Shape} GObjects, and use a GTypeModule-based

Sat Aug  2 23:19:16 2003  Owen Taylor  <otaylor@redhat.com>

        * pango/pango-engine.[ch] modules/*/*-{fc,win32,x}.c
        pango/modules.c pango/break.c pango/pango-context.c
        pango/pango-layout.c pango/pango-modules.h
        pango/querymodules.c pango/shape.c: Make
        PangoEngine{,Lang,Shape} GObjects, and use a
        GTypeModule-based module-loading system closely based
        on the one used for GtkIMContext and GtkThemeEngine.

        * pango/pango-impl-utils.h: OK, I'm tired of typing
        in get_type() functions.

        * pango/pango-script.[ch] pango/pango-script-table.h
        tests/testscript.c tools/gen-script-table.pl: Add port
        of script-range code from ICU in preparation for future
        use. (#91542)

        * tools/gen-script-for-lang.c: Utility program to determine
        the script for each fontconfig .orth file.

        * docs/tmpl/{scripts.sgml,pango-engine-lang.sgml,
        pango-engine-shape.sgml} docs/pango-sections.txt docs/pango-docs.sgml:
        Redo to go along with the above changes.

        * configure.in: chmod +x tests/runtests.sh
