Summary: RFE: text along path
Initial Comment:
The attached diff implements typesetting of text along
a path as a decorator (curvedtext). I put it in the bug
tracker so that it doesn't get lost. It's a diff to
r2824 (taking into account the reversal of trafos in
canvas.py (r2728->r2730)).
From the docstring:
"""a text decorator for curved text
- text: is typeset along the path to which this
decorator is applied
- relarclenpos: position for the base point of the
text (default: 0)
- arlenfrombegin, arclenfromend: alternative ways
of specifying the position of the base point;
use of
relarclenpos, arclenfrombegin and arclenfromend is
mutually exclusive
- textattrs, texrunner: standard text arguments
(defaults: [] resp None)
"""
Files touched aside from deco.py:
dvifile.__init__() in dvifile.py gets a new parameter
singlecharmode which defaults to 0; dvifile.putchar()
switches to single character mode if set to 1.
texrunner.__init__(), texrunner.finishdvi(),
texrunner.text() and texrunner.textboxes() in text.py
get the same parameter so that it can be passed from
the texrunner to dvifile.
curvedtext switches to singlecharmode only while it is
needed.
Basic idea for curvedtext goes back to schindmi, I think.

Hello Michael,
In principle I have nothing against this implementation.
The only small things I noted are that our formating
style is not followed everywhere (spaces are =), docstrings
for the class in __init__, etc. And adding documentation
would be nice too!
Jörg
PS: Not wanting to insist, but the idea and the
implementation go back to me, although schindmi lost
one afternoon of our precious worktime playing around with
it, as well.

Attaching a simple example:
It demonstrates how to achieve several orientations using
text.halign.*, relarclenpos and path.reversed(); and how to
set different stroke attributes on the text and the
underlying path.
