           Summary: [cairo] missing cairo_stroke_to_path to complete ink's
                    drawing attributes
           Product: Moonlight
           Version: 1_0
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Minor
          Priority: P5 - None
         Component: media

The lack of the function cairo_stroke_to_path is blocking some Silverlight
features for DrawingAttributes. As such Moonlight only supports a subset of the
DrawingAttributes used to draw ink strokes.

The two main limitations are:

(a) we cannot implement correctly the OutlineColor property. Instead we hack
around this limitation by drawing a the strokes two times, first time a bit
larger (+2) using the outline color then a bit smaller (-2) using the normal

(b) we approximate the path to a line. This means that we have a single way to
specify the line (cairo_set_line_width) instead of building a path were both
different width and height can be supplied.
