I'm favouring the imperative here, they both seem equally poor constructs so I'm not going to change them for the sake of change...

Fixed.

Mispelling of cairo_set_line_width() fixed.

The '#' is gtk-doc markup to generate a cross-reference to the definition of CAIRO_STATUS_INVALID_DASH.

Won't fix. cairo_stroke_to_path() will be implemented one day.

Duplicate 'operation' removed.

Text updated to refer to cairo_clip_preserve().
