Yeah - I tried having a quick 5 minute look at that today but didn't
succeed. Actually, it seems like thumbnail.c is the least of the issues,
it's more that it has to be handled in automatically included
scalers/converters (I'm surprised they don't seem to handle it at all),
and in the vmem video output.
