Original commit message from CVS: 2005-11-18 Julien MOUTTE <julien@moutte.net> * sys/ximage/ximagesink.c: (gst_ximage_buffer_finalize), (gst_ximagesink_check_xshm_calls), (gst_ximagesink_ximage_new), (gst_ximagesink_ximage_destroy), (gst_ximagesink_xwindow_draw_borders), (gst_ximagesink_ximage_put), (gst_ximagesink_xwindow_new), (gst_ximagesink_xwindow_update_geometry), (gst_ximagesink_handle_xevents), (gst_ximagesink_event_thread), (gst_ximagesink_xcontext_get), (gst_ximagesink_xcontext_clear), (gst_ximagesink_bufferpool_clear), (gst_ximagesink_getcaps), (gst_ximagesink_setcaps), (gst_ximagesink_change_state), (gst_ximagesink_show_frame), (gst_ximagesink_buffer_alloc), (gst_ximagesink_navigation_send_event), (gst_ximagesink_set_xwindow_id), (gst_ximagesink_expose), (gst_ximagesink_set_property), (gst_ximagesink_get_property), (gst_ximagesink_finalize), (gst_ximagesink_init), (gst_ximagesink_class_init): * sys/ximage/ximagesink.h: Refactoring of ximagesink. This new version brings correct software scaling, non flickering window while resizing, pixel aspect ratio handling, usage of hardware buffer pools, out of data flow event thread for navigation and handling of expose events even when being PAUSED, a new property to keep video aspect ratio when resizing, etc...
