/* Todo:
 * - Some browsers don't scale SVGs properly; the img container

 *   if this only applies to Internet Explorer or if it applies to
 *   other uncommon browsers too. If any non-IE browsers do this and/or
 *   if the spec allows this behavior, try to correct it here.
 * - Wait till Webkit fixes its broken-ass default dark stylesheet
 *   then consider trimming the dark stylesheet I provide.
 * - Investigate CSS-based hints to screenreaders. */
