Subject: latin: common styling for svg paths (lines)
X-Git-Tag: v1.10~308

latin: common styling for svg paths (lines)

SVG data is always inlined, so making it dependent on page style should not
be an issue.  Simplifies all paths to be lines unless fill is specified,
decreasing total size from 46kB to 38kB (though only 50 bytes over 4kB
compressed).
