gst/videofilter/gstvideobalance.c: Fixing videobalance ranges for colorbalance interface implementation.

Browse source 
Original commit message from CVS:
2004-01-14  Julien MOUTTE  <julien@moutte.net>

* gst/videofilter/gstvideobalance.c: (gst_videobalance_init),
(gst_videobalance_colorbalance_set_value),
(gst_videobalance_colorbalance_get_value): Fixing videobalance ranges
for colorbalance interface implementation.
* sys/ximage/ximagesink.c: (gst_ximagesink_xcontext_get),
(gst_ximagesink_set_property), (gst_ximagesink_get_property),
(gst_ximagesink_dispose), (gst_ximagesink_init),
(gst_ximagesink_class_init): Adding DISPLAY property.
* sys/ximage/ximagesink.h: Adding display_name to store display.
* sys/xvimage/xvimagesink.c: (gst_xvimagesink_xcontext_get),
(gst_xvimagesink_set_property), (gst_xvimagesink_get_property),
(gst_xvimagesink_dispose), (gst_xvimagesink_init),
(gst_xvimagesink_class_init): Adding DISPLAY property and colorbalance
properties (they still need polishing though for gst-launch use : no
xcontext yet, i ll do that tomorrow).
* sys/xvimage/xvimagesink.h: Adding display_name to store display.
