Ha! They're hard to miss that way :)
Rendering them at any given pixel size is fairly easy:
if their default size is w0xh0 say, and you want them at w1xh1,
then allocate your suface at w1xh1 size, and before the call to
the rsvg-render function, add the cairo call
cairo_scale(cr, w1 / (double)w0, h1 / (double)h0);
or
cairo_scale(cr, w1 / dim.em, h1 / dim.ex);
Actually, just for testing purposes, as things stand,
see if adding the call
cairo_scale(cr, dim.width / dim.em, dim.height / dim.ex);
does anything differently than what it does now (it shouldn't,
but...).
