[Therion] The goal with joining scraps

[torstein finnesand]

Hi folks, some questions about the join command.

We join scraps to make nice pdf-maps or other two-dimensional maps like 
svg, xhtml and kml. Of course, this is a very good reason.

1. But are there other reasons to do it?
For instance, do joins have any influence on other exports, like the 
maps (walls) in aven or the models in loch? I did a simple preliminary 
test, and couldn't find any difference whether the scraps were joined or 
not.

2. Do you always joins the scraps?
Are there some situations when its not necessary, or even wrong, to join 
scraps?
