Add an async renderer interface (method + callback) which is useful for

2005-06-07  Marco Pesenti Gritti <mpg@redhat.com>

        * backend/Makefile.am:
        * backend/ev-async-renderer.c: (ev_async_renderer_get_type),
        (ev_async_renderer_class_init), (ev_async_renderer_render_pixbuf):
        * backend/ev-async-renderer.h:

        Add an async renderer interface (method + callback) which
        is useful for backends like ps.

        * backend/ev-job-queue.c: (remove_job_from_async_queue),
        (add_job_to_async_queue), (job_finished_cb), (handle_job),
        (ev_job_queue_run_next), (ev_job_queue_init), (find_queue),
        (ev_job_queue_add_job), (move_job_async), (move_job),
        (ev_job_queue_update_job), (ev_job_queue_remove_job):

        Add queues for async renderer, these are executed on the
        main thread.

        * backend/ev-jobs.c: (ev_job_render_new), (render_finished_cb),
        (ev_job_render_run):
        * backend/ev-jobs.h:

        If the backend support async renderer interface use it.

        * ps/ps-document.c: (ps_document_init), (push_pixbuf),
        (setup_pixmap), (ps_document_get_type),
        (ps_async_renderer_render_pixbuf),
        (ps_document_document_iface_init), (ps_async_renderer_iface_init):

        Implement async renderer interface.
