Summary0000143: SVG rendering bug

In svggen.c:

1) Scale is not consistently applied when emitting cp->fontsz
(though we could quibble about whether we want to do this once
at the head of the entire SVG output or not). It is true that
the default coord system in SVG is pixel space.

Even if you correct, this there are other problems.

2) The code gen calls svg_set_font() when it starts up
to initialize the default font, but svggen.c doesn't do
anything with the values except save them on cstk[] !

3) The code in svg_font() that apparently is trying to
set the SVG environment to be consistent with cstk[] checks
against cstk[0] not cstk[SP]!

4)Designing svg_font() in this way means it can't easily be
called by svg_set_font() to establish the initial environment.

Thus examples like
    digraph G {
        node [fontsize=32]
        a [label="A Good Deal\nand a Good Deal More"];

come out wrong because the font is never set to 32 (or 32 * 96/72,
