Broken graphics in a WPF window when using GStreamer

[Holger Kaelberer]

Hi,

this sounds like what we saw on Linux/XWindows with video-sinks not handling expose events (don't 
know what the Windows equivalent is).

We solved it by filtering out Expose XEvents in the application from further event-processing by the 
GUI framework (Qt) and calling gst_x_overlay_expose() on the video-sink for them instead.
