SVG generation bug for OttavaSegment

[eiffel31]

Issue type

Import/export issue

Bug description

When ottava alta or bass are used, the generated SVG file is not usable with common tools such as inkscape or openoffice.

Steps to reproduce

Create new score, add few notes with ottava, export as SVG.
Open the SVG file with inkscape: big display problems, zoom dependant
If the SVG is imported in openoffice document, the vertical part of the ottava delimiter is not displayed.

In the generated SVG file, there are 2 polylines for the ottava segments. The vertical one defines a "stroke-dasharray" with a negative value. Removing the minus sign solves the display problem.

I just edited a new .svg file, here is the changes I made with a text editor in the produced svg file:
<polyline class="OttavaSegment" fill="none" stroke="#33d17a" stroke-dasharray="16.501,-6.62542" stroke-dashoffset="0" stroke-width=...
Turned into:
<polyline class="OttavaSegment" fill="none" stroke="#33d17a" stroke-dasharray="16.501,6.62542" stroke-dashoffset="0" stroke-width=...
(minus sign removal in stroke-dasharray definition)

Seems to be a Mu3 regression

I just observed the same problem with a "dim._ _ _"
<polyline class="HairpinSegment" fill="none" stroke="#000000" stroke-dasharray="17.856,-13.599" stroke-dashoffset="0"...
The minus sign has to be removed in the stroke-dasharray definition.

I suspect it'll be an issue what all dashed lines
