According to http://doc.iridas.com/index.php?title=LUT_Formats

    for 3D textures, the data is also RGB, and ordered in such a way
    that the red coordinate changes fastest, then the green coordinate,
    and finally, the blue coordinate changes slowest:

Fixes Ticket #3236.

Its usefull to know immediatly if extradata is wrong and not just when later
the decoder tries to use it.

The error was fixed in commit ce9bd303
more than one year ago, and does not affect all the currently supported
versions.

In particular, fix trac issue #1535.

It has been disabled as 'broken' over 3 years ago in b716a792

This introduces some code duplication. However, much of it should go
away once the decoders stop using MpegEncContext.
