// global async_test, assert_equals
//
// This test generates a couple of scenarios (each a
// SVGSizing.TestData) for sizing inline <svg> and uses a simple
// JavaScript sizing implementation for comparison.
//
// The tests loops through different combinations of:
//
// * width and height attributes and style on <svg>
//
// * viewBox on <svg> (gives intrinsic ratio)
//
// * width and height on containing block of <svg>
//
// All these may contribute to the final size of the SVG. The test
// focuses on the size of the CSS box generated by the SVG. Little
// focus is put on variations within an attribute that doesn't affect
// the final size.
//
// To debug a specific test append ?<test-id> to the URL. An <iframe>
// is generated with equivalent test and the source of the test is
// added to a <pre> element.
