I notice that the palette inclusion is only made by using 'xxpc' chunks 
in the video data so far. I'm not so sure if these in-data palette 
changing chunks are widely supported. Therefore, first and foremost, and 
the most widely supported way in my book, is to add an "initial" palette 
after the BITMAPINFOHEADER in the strf chunk. That's where I found it to 
be a bit tricky, but I'm sure you can solve it in some way.
