Okay, I've tried the testcase across the SVG implementations:

Safari 4 (latest release)
FAIL path.getPathSegAtLength(0) should be 0. Was 1.
FAIL path.getPathSegAtLength(1) should be 0. Was 1.
PASS path.getPathSegAtLength(5) is 1
PASS path.getPathSegAtLength(6) is 1
FAIL path.getPathSegAtLength(10) should be 2. Was 1.
FAIL path.getPathSegAtLength(11) should be 2. Was 1.
FAIL path.getPathSegAtLength(16) should be 0. Was 1.

Opera 10.10

FAIL path.getPathSegAtLength(0) should be 0. Was 2.
FAIL path.getPathSegAtLength(1) should be 0. Was 2.
FAIL path.getPathSegAtLength(5) should be 1. Was 2.
FAIL path.getPathSegAtLength(6) should be 1. Was 2.
PASS path.getPathSegAtLength(10) is 2
PASS path.getPathSegAtLength(11) is 2
FAIL path.getPathSegAtLength(16) should be 0. Was 3.

FireFox trunk (Minefield)

PASS path.getPathSegAtLength(0) is 0
FAIL path.getPathSegAtLength(1) should be 0. Was 1.
PASS path.getPathSegAtLength(5) is 1
FAIL path.getPathSegAtLength(6) should be 1. Was 2.
PASS path.getPathSegAtLength(10) is 2
FAIL path.getPathSegAtLength(11) should be 2. Was 3.
FAIL path.getPathSegAtLength(16) should be 0. Was 3.

I think FireFox does it right.
The path is auto-closed because of the last segment, so the distance=16 should
actually say 3 IMHO.
