Revert of more zero-length changes for svg compatibility (patchset #6 id:100001 of https://codereview.chromium.org/1330623003/ )

Reason for revert:
breaks DEPS

Original issue's description:
> more zero-length changes for svg compatibility
>
> If a path contains a moveTo followed by a line or curve,
> even if the line or curve has no length, SVG expects
> the end caps to draw if the cap style is round or square.
>
> Fredrik Söderquist attached a patch to the chrome bug
> (slightly modified here) that fixes layout test failures
> resulting from deleting special-case code in SVG
> dealing with zero-length path segments.
