stroke outline does not preserve miterlimit

[Buliabyak-users]

I fixed all the commands in splivarot so that they use
the actual style->stroke_miterlimit.value instead of
the preset value of 4. However, outline still does not
preserve the shape. Load the attached file and convert
its strokes to paths; various misbehaviors occur, as
indicated in the file.

_Almost_ fixed. All the samples in the attached file are now
outlined correctly, except one. I now attach a new file with
that one sample in which the long miter is cut when outlined.

still there...

Imo the behaviour of the outline (path to stroke) is correct, but the joins are rendered incorrect.

The join in the attached file is 5,71 deg in all cases (left side is the stroke, right side is the stroke converted to path). The corresponding miter limit at which the join is expected to change from bevel to miter is 20,075 (spec).

- Joins with straight line ends are correct -> top case in attached files.
- With bent line ends (bottom case) the behaviour of the 'stroke to path'-side is correct, while it seems that for a given miter limit the renderer allows to long miters.
