+Bug 1014547 - CSS transforms highlighter
+Test that the highlighter elements created have the right size and coordinates.
+
+Note that instead of hard-coding values here, the assertions are made by
+comparing with the result of getAdjustedQuads.
+
+There's a separate test for checking that getAdjustedQuads actually returns
+sensible values
+(devtools/client/shared/test/browser_layoutHelpers-getBoxQuads.js),
+so the present test doesn't care about that, it just verifies that the css
+transform highlighter applies those values correctly to the SVG elements
