sys/ximage/gstximagesrc.*: Fix use-damage property to actually work :)

Browse source 
Original commit message from CVS:
2006-07-09  Zaheer Abbas Merali  <zaheerabbas at merali dot org>

* sys/ximage/gstximagesrc.c: (gst_ximage_src_ximage_get),
(gst_ximage_src_set_property), (gst_ximage_src_get_property),
(gst_ximage_src_get_caps), (gst_ximage_src_class_init),
(gst_ximage_src_init):
* sys/ximage/gstximagesrc.h:
Fix use-damage property to actually work :)
Add startx, starty, endx, endy properties so screencasts other than full
screen ones can work.
