Is your SVG file designed to cope with that kind of scale? That is,
is it designed such that it only has coordinates from 0.0 to 1.0 ? If
not, you might be simply scaling the image entirely off the
surface. So maybe try again without the cairo_scale in there and see
what happens, (which should draw the SVG file such that one unit in
the SVG file corresponds to one pixel).

Well, white's not all that reliable of a color. Maybe try something
like:

	cairo_set_source_rgb (cr, 0.0, 1.0, 1.0); /* cyan */

instead?

I won't comment on whether it's a mistake or not, but cairo is
supposed to function on that platform.
