Macro rsvg::test_svg_reference

macro_rules! test_svg_reference {
    ($test_name:ident, $test_filename:expr, $reference_filename:expr) => { ... };
}

Render two SVG files and compare them.

This is used to implement reference tests, or reftests. Use it like this:

use rsvg::test_svg_reference;
test_svg_reference!(test_name, "tests/fixtures/blah/foo.svg", "tests/fixtures/blah/foo-ref.svg");

This will ensure that foo.svg and foo-ref.svg have exactly the same intrinsic dimensions, and that they produce the same rendered output.
