JpegData method missing

[Mike-3]

After upgrade to 4.0, I can't found not the class JpegData or a suitable alternative. I need the comment and adobe data. What is the new way of getting this information?

I needImage.blendMethod and Image.channels as well :(

Sorry for the delay, I'll get back to you as soon as I can.

I pushed a change to git to add JpegData back to the export list for the library. I'll see if there's a better way to get that info into the Image class so you don't need to access the low level JpegData class, but life is pretty hectic right now so I might not be able to get to it for a bit.

@S-Man42 blendMethod was used to specify what type of compositing was needed for partial animated frames, but now all frames are always complete frames, so they don't need explicit compositing. That's why it was removed. Image.channels just informed you if the alpha channel was to be used or not since all images always had 4 channels. Now images can have variable number of channels, so numChannels tells you how many channels the image has, typically 3 (rgb) or 4 (rgba).

I know for such a big change as 3.0 to 4.0 it really needed good "what changed" documentation, but really I ran out of time, and I'm not very good at writing documentation.
