Documentation:
How to vaporize lines that are cut off.

Accept this many characters cutting off a line and still treat
it as one line.
Example:
If `artist-vaporize-fuzziness' is 2, then those will be recognized as
lines from A to B (provided you start vaporizing them at the ``*''):
/
A----*------/-----------B
\/
A----*----/\------------B
/ \

but this one won't, since it is cut off by more than 2 characters:
\/ /
A----*----/\/----------B
/ /\
(in fact, only the left part [between the A and the leftmost ``/''
crossing the line] will be vaporized).

You can customize this variable.
