Space character handling in SVG output

[tk0miya]

environment: seqdiag 0.9.5 (installed by pip) on macOS

For the diag below includes spaces to represent code indent in note,
png output shows these spaces as is, but SVG output does not.
Precisely speaking, SVG text has spaces in text tag, then consecutive
space characters collapse to (much) narrower spacing.

seqdiag {
  a; b;
  a -> b [label = "foo",
leftnote =
"
1| case a of
2|     1 -> true;
3|     2 -> false
4| end
"];
}

Extraction from output SVG:

  <text fill="rgb(0,0,0)" font-family="sans-serif" font-size="11" font-style="normal" font-weight="normal" text-anchor="middle" textLength="64" x="64.0" y="134">1| case a of</text>
  <text fill="rgb(0,0,0)" font-family="sans-serif" font-size="11" font-style="normal" font-weight="normal" text-anchor="middle" textLength="86" x="75.0" y="147">2|     1 -&gt; true;</text>
  <text fill="rgb(0,0,0)" font-family="sans-serif" font-size="11" font-style="normal" font-weight="normal" text-anchor="middle" textLength="83" x="73.5" y="160">3|     2 -&gt; false</text>
  <text fill="rgb(0,0,0)" font-family="sans-serif" font-size="11" font-style="normal" font-weight="normal" text-anchor="middle" textLength="35" x="49.5" y="173">4| end</text>

Sorry, this problem is caused from behavior of buildout.
We can't fix it.

I think separate build target and try to install in second phase::

• bin/buildout install pillow
• bin/buildout install extra
