* sys/ximage/ximagesink.c: (gst_ximagesink_renegotiate_size),
(gst_ximagesink_calculate_pixel_aspect_ratio),
(gst_ximagesink_xcontext_get), (gst_ximagesink_getcaps),
(gst_ximagesink_sink_link), (gst_ximagesink_change_state),
(gst_ximagesink_set_xwindow_id), (gst_ximagesink_set_property),
(gst_ximagesink_get_property), (gst_ximagesink_init):
* sys/ximage/ximagesink.h:
allocate PAR's dynamically.
use autodetected PAR if no object-set PAR is given.
add workaround for directfb's X not setting physical size.
fix to xvimagesink will follow tomorrow.
