           Summary: Goom visualization is unusable at 'Normal' size and
                    higher

"Goom visualization works as expected as 'Small' size. But if I increase it to
'Normal', 'Large' or 'Extra Large', totem sucks up 1 CPU to 100% (I use P4 HT),
and the sound output becomes choppy or no output at all. Visualization is
invisible too.

However, sometimes it is possible to restore it to working normally by dragging
the possition slider, pausing/unpausing etc. Then CPU usage drops back to ~10%
on 'Normal' size, ~25% on Large size (average from both virtual processors). So
CPU it is capable of doing those Gooms at realtime, the problems lie somewhere
else.

Im not sure, but IIRC it is a regression from Flight5-6 where it worked fine.

I attach the part of GST_DEBUG=3 totem output.
