The C++ tutorial is very similar to the C tutorial which went through M3, so it's generally fine.
Concerns / issues
- The tutorial is a little long given that it's a task a lot of people will need to perform. If there's any way to make it shorter (even less wordy), that would be great. But it's not a major concern given that the explanation is clear.
- The question I could see people asking is, when sharing the image data, how long does the data persist? How long can I hold onto the data? Are there any negative consequences to sharing the data if processing will take a long time?
