Hi Stefan and list,

I've been working on the SignWriting Image Server.  I updated the 
display function to output horizontal writing.

I tried out a new style of layout for horizontal writing and I'd like 
your feedback.  Here's the output for 4 signs and 1 punctuation.

This uses a technique similar to vertical writing because it uses lanes 
and offsets.  There are 2 lanes: a middle lane and an upper head lane.  
Punctuation is always centered in the middle lane.  The second and the 
fourth signs are centered in the middle lane.  The first and third signs 
are centered in the head lane.  Any sign that has head symbols is 
vertically offset upwards into the head lane.

Signs written in the overhead view may cause complications, but 
otherwise I think the idea is solid.

Thoughts or feedback would be appreciated.
