Revert of experiment with zero-length round capped line segments (patchset #4 id:60001 of https://codereview.chromium.org/1309753002/ )

Reason for revert:
More GMs changed than I expected. Will probably affect layout tests as well; reverting until I can verify that the changes are correct.

Original issue's description:
> experiment with zero-length round capped line segments
>
> If the endcap is not butt, draw the endcaps even when the line
> has zero length.
>
> If the dash length is zero, generate a zero length line segment.
>
> Treat a move followed by a close as a move followed by a zero-length
> line.

         contour (e.g. lines).
-
-        If the cap is round or square, the caps are drawn when the contour has
-        a zero length. Zero length contours can be created by following moveTo
-        with a lineTo at the same point, or a moveTo followed by a close.
-
-        A dash with an on interval of zero also creates a zero length contour.
-
-        The zero length contour draws the square cap without rotation, since
-        the no direction can be inferred.
