        Bug 328067 – Install pango-view

        Added a rather generic framework for a pango-view example.  All
        backends have their own pango*-view built, and a pango-view binary
        is built too, that can choose backend via --backend.  This one is
        installed in bindir.

        * examples/Makefile.am: Updated, to build pangox-view, pangoft2-view,
        pangoxft-view, pangocairo-view, and pango-view.

        * examples/viewer.h, examples/viewer-x.c, examples/viewer-x.h
        examples/viewer-cairo.c, examples/viewer-cairo.h,
        examples/viewer-main.c, examples/viewer-pangox.c,
        examples/viewer-pangoft2.c, examples/viewer-pangoxft.c,
        examples/viewer-pangocairo.c, examples/pango-view.c,
        examples/pango-xview.c, examples/pango-ft2view.c,
        examples/pango-xftview.c, examples/pango-cairoview.c: Added.

        * examples/cairoview.c, examples/xftview.c, examples/pangoft2topgm.c,
        examples/viewer-qt.cc, examples/viewer-qt.h: Removed.

        * configure.in: Check for Cairo Xlib backend, also AC_DEFINE various
        backend bits.
