+// 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 on <object>, <iframe> (input dependent)
+//
+// * width and height on <svg>
+//
+// * viewBox on <svg> (gives intrinsic ratio)
+//
+// * width and height on containing block of <object>
+//
+// All these contribute to the final size of the SVG in some way.
+//
+// The test focuses on the size of the CSS box generated by the SVG.
+// The SVG is always empty by itself so no actual SVG are tested.
+// Little focus is put on variations within an attribute that doesn't
+// affect the sizing behavior.
+//
+// To debug a specific test, append ?<test-id> to the URL. An <iframe>
+// is generated with equivalent test and the source code of the test
+// can be downloaded.
