[libgd/wip/rishi/modernize-gobject: 2/5] toggle-pixbuf-renderer: Use G_DEFINE_WITH_PRIVATE

[Debarshi Ray <debarshir src gnome org>]

commit 6d254dc701b8b29745edd54ff4e7643a8feeb8a1
Author: Debarshi Ray <debarshir gnome org>

    toggle-pixbuf-renderer: Use G_DEFINE_WITH_PRIVATE
    
    This paves the way for improving our GObject use and reducing the
    amount of boilerplate.
    
    G_DEFINE_WITH_WITH_PRIVATE was introduced in GLib 2.38, which should be
    old enough for all users.
