[Michael Natterer <mitch src gnome org>]

commit 96ebc6f8486e0cf7efa45d491736062dfd6364b0
Author: Michael Natterer <mitch gimp org>
Date:   Wed Apr 25 12:09:45 2012 +0200

    app: add "new_precision" argument to gimp_drawable_convert_type()
    
    for clarity and consistency with the "new_base_type" argument.
