SVG: (SVG 1.1) arcs sensible to zoom level

This is the first of a series of SVG-related bug reports, made in the
scope of the version 10 pre-release announcement. I've decided to
create a new thread for each bug which, although somehow cluttering,
will help isolating the discussion for each separate issue. All issues
were previously checked in known open bugs list [1], wish list [2] and
searched in the mailing list [3] prior to submission.


Release number:
amaya 10 (Feb 1 2008)

Platform:
Windows XP SP2

Description of the bug:
(SVG 1.1) arcs are affected by zoom level. By observing the behavior
it's suggested that the control vectors are the portion which seem to
be affected.
This may deceive the user as the arc may assume another appearance
(straight line when the document is zoomed out, for example) and a
causes weird visual effects. Begin and end coordinates seem OK.

Example to reproduce the bug:
1. Open attachment "arcs-control-vectors.svg";
2. Zoom the document in/out (using Ctrl+mouse wheel scroll, for example).

Scenario where the bug occurs:
Although the issue was isolated in the file attached, it seems to
occur whenever (SVG 1.1) arcs are used.

Additional notes:
This is related to the (somehow too generic) bug SVG005. The bug
report contains an URL [4] where the clouds in "Weather" button also
suffer from the issue.
