Bug ID: 123384
Issue Type: DEFECT
Summary: [SVG] marker direction must not depend on length of
path segment
Product: Draw
Version: 4.1.0-dev
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: P3

Draw document with linked SVG graphics.
The marker direction must only depend on the angle of the path segment, not on
the length. See "11.6.2 The ‘marker’ element" in
http://www.w3.org/TR/SVG/painting.html
"A value of 'auto' indicates that the marker is oriented such that its positive
x-axis is pointing as follows:
If there is a path segment coming into the vertex and another path segment
going out of the vertex, the marker's positive x-axis should point toward the
angle bisector for the angle at the given vertex, where that angle has one side
consisting of tangent vector for the path segment going into the vertex and the
other side the tangent vector for the path segment going out of the vertex."
Therefore in all cases in the attached example, the direction of the marker-mid
has to be 315°, which is middle of 0° from h command and 270° from v command.
The graphics are linked, so that you can easily see, how they are rendered in
browsers.
