Adding focus points for cameras

[Gilles Caulier]

Hi all,

Please open a file in Bugzilla about this topic and add all relevant
information as comments. Mailing list  threads time-to-live is
limited. In bugzilla all is archived in a database and complex queries
help to manage the project in time.

In other words, Bugzilla is the project backbone.

Thanks in advance

Gilles Caulier
