Original commit message from CVS: * gst/videofilter/gstvideobalance.c: Fix regression; changing a property affects the video stream. * sys/xvimage/xvimagesink.c: * sys/xvimage/xvimagesink.h: Add synchronous property for debugging. Should probably be disabled in non-CVS builds. Make sure that the Xv attribute exists before we set it (crash!). Fix a silly float bug that caused colorbalance to just not work.
