P: Add ability to have borders around pictures in the Book Module

I would suggest to re-name current functionality in print module / custom package:
"Photo border" does not add a line of a specified width currently, as I would expect from the term.

But it puts padding around the picture of the specified width, i.e. free outer space.
So what about calling current 'Photo border' 'Photo padding' ?

Then if you follow my version of this feature request, use the term "border" for both the inner and outer stroke.

Update this in Print Module as well as adding it to Book Module.

I would want one more related thing: to be able to add 2 borders:
1. an outer stroke, a small black line (but please give choice for colour and pixel width)
2. an inner stroke, broader and white-ish (just give the same choice for colour and pixel width).

Ideally I could have this both in Print Module/custom package
and in the new Book Module.

I would like to define this as standard/preset for any new image box I put on a template.

Use case: to have a passe-par-tout like layout, which is clean and simple.
It is especially good looking of you have a semi-transparent image as background underneath as it separates the pictures on top better than using shadows.
Of course that is subject to personal taste.
But my specification is flexible enough so everybody can use it partially or not at all.
