[GRASS5] several questions on imagery commands

[Moritz Lennert]

Hello all,

In the course of writing up a first draft of the chapter on image
processing for the GRASS tutorial, I stumbled upon a few questions:

- Do people still use the i.tape.* commands ?

- Is there any reason to use i.points and i.rectify instead of i.points3
and i.rectify3 ?

- Is there any significant difference between i.composite and r.composite ?

Any help is appreciated.
