I create the layout after the matrix is set, and, not knowing how the API
works, I also called pango_cairo_update_layout after selecting the font
size.  The odd thing is that the spacing scales with the CTM, but the
glyph sizes do not.

I'll read through the SVG spec and see whether this is always true; it may be
that SVG allows applications to request text wrapping or embed newlines.
