dithering: small fix for display of scaled down images
Factorize code to compute image offset in collection.
Fix film strip offset computing.

This may be due to a bug in SQlite as the request of the form:

   select rowid from (select * from images);

returns a suite of empty lines instead of the rowid. This was used
to compute the offset of the filmstrip and so the selected image
was never properly put in the center.

The workaround is to do part of the computation directly in C.

Add new dialog to copy part of ops.

This will be used in lightable and in the darkroom filmstrip to select
the ops to copy in the history. Currently all the history is copied.
Add new dialog to copy only parts of the history.

This is activated by default on the lightable were ctrl-c and copy button
does a partial copy now. The dialog has a "copy all" button which should
be easy to use to get the previous behavior. In the film strip the ctrl-c
is mapped to the partial history copy (with the dialog) and a new action
mapped on ctrl-shift-c can be used to copy all history.
Add support for paste on selection in the filmstrip.
Swedish update
Show all folders that are also filmrolls
