Another interesting thing about symbols I didn't know about
@ symbols in labels, and I don't think is documented:
The more lines in the string, the larger the symbol will be;
the symbol is scaled to the size of all lines, and centered.
Here comes some examples that use ascii art (view in a
fixed width font!)
If the label string is:
"@< Aaa\nBbb @>"
You'll get:
/| Aaa |\
\| Bbb |/
..and if the string has more lines, e.g.
"@< Aaa\nBbb\nCcc\nDdd @>"
..then you'll get larger arrow symbols matching the height of all
the lines:
/| Aaa |\
/ | Bbb | \
\ | Ccc | /
\| Ddd |/
..instead of what I was *expecting*, which would have been:
<| Aaa
Bbb
Ccc
Ddd |>
This behavior of symbols automatically centering + scaling
should really be documented too.
I had no idea symbols worked this way until I looked closely
at the side effects of fl_measure's code.
