[Cin] add Frame on PiP on manual

[Igor BEGHETTO]

About "I propose to post the contributions to the mailing list in odt so 
that any user can propose, read and edit them."

It is my fault, sorry.
It's probably best to continue as you did because it is more efficient, 
as far as I understand. If someone, like me, has to add something, 
temporarily the ODT or simple text could be adopted (and uploaded on 
https://transfer.sh/).
Sorry again.
