Summary: Strange OSD rendering

Initial Comment:
I am building a plugin for SVCD OGT subtitles that
writes on an OSD to achieve its effect.  I am having a
very strange effect where pixels with some colors are
rendered shifted wrt pixels with other colors.

I am not completely sure this is a bug in xine, but I
have written code to dump the osd data right before
showing it and does not exhibit this behaviour.   It is
some effect of the overlay rendering, possibly due to
some misunderstanding on my part.

I would have reported this on xine-devel only, but I
did not consider it appropriate to send large files
there.  I will raise the topic there, though.

Thanks,

Julio

The overlay blending has been improved by Reinhard Nissl in 
xine-lib 1-rc6a, so this might have improved. (The problem 
cannot be fixed easily because of the colourspace subsampling 
used for the video frames.)
