It's good news!

I have some bugs I filed.

* PopplerAction family is not GLib-ish
  https://bugs.freedesktop.org/show_bug.cgi?id=6912

  Now, I think this idea isn't good because GdkEvent uses
  same implementation. So I'll close this bug. Any opinion?

* make PopplerFontInfo GObject
  https://bugs.freedesktop.org/show_bug.cgi?id=6921

  I'm the maintainer Ruby/Poppler. It's very easy to
  implement Ruby bindings if an object supports G_TYPE. I
  think it's a good idea that PopplerFontInfo supports
  GObject not GBoxed. Because PopplerFontInfo has a
  FontInfoScanner and FontInfoScanner doesn't have copy
  constructor. That is PopplerFontInfo's copy function can't
  copy current scan information. So, I think GObject is a
  good choice rather than GBoxed.

* It's better PopplerPage manages PopplerDocument's reference count
  https://bugs.freedesktop.org/show_bug.cgi?id=7005

  This request is for Ruby bindings too.

  A problem case is the following(Ruby):

    doc = Poppler::Document.new(input)
    page = doc[0]
    doc = nil
    GC.start # doc is garbage collected and
             # g_object_unref(doc) is called.
    page.render_to_pixbuf(...) # uses (destroyed) page->document
                               # internally and causes
                               # segmentation fault

  For now, Ruby/Poppler guards doc from GC until page is
  stile alive. But this is just work around.
