> This is mostly straightforward. The major complication is that, as a
> result of the 16-bit chunk size limitation, ICC profiles may need to be
> split up into multiple chunks.
> 
> We also need to make sure to allocate enough extra space in the packet
> to fit the ICC profile, so modify both mpegvideo_enc.c and ljpegenc.c to
> take into account this extra overhead.

> I will submit a FATE patch and test separately. (We do not currently
> have any JPGs with embedded ICC profiles in the test suite)
