[Ssc-dev] It works!

[Andrew Senior]

Hey, that's great. That looks like a sensible sequence.

The "rawgrey.pgm" is really a debugging thing- it returns the image that I
get by decoding the intensity DC coefficients of each block, so ignoring
colour, and giving an 8x8 downsampling.
You should be able to supply NULL to that parameter and it will be ignored.
However, since you're using "ParseImage", you're not using the latest
version of the repository (now DecodeImage IIRC), so perhaps I didn't fix
that check-for-null.
In practice it doesn't make sense to have this debugging parameter in there,
so I'll get rid of it.
Let me know what things needed shifting around, and we can work out what the
best way is, especially as I've checked in some changes since. Let me know
your github ID and you can have write access.
Andrew
