 Fix Seg Fault due to OSD painter being deleted while image loader threads
 are still using it.

 Image loading for the OSD uses ImageLoadThread and continues
 loading while the video is playing. If the video playback
 encounters an "InputChanged" situation it deletes the OSD and its
 painter and re-creates it.  If the Image load is still running and
 using the painter, it gets a Seg Fault calling a virtual function
 using a corrupted object

 Exception Details:
 1   in MythPainter::GetFormatImage at mythpainter.cpp:540

 Fix: Keep the old osd painter valid until either it changes again
 or the OSD is deleted.
