// Spec: http://dev.w3.org/SVG/profiles/1.1F2/publish/coords.html#ViewportSpace
// The SVG user agent negotiates with its parent user agent to determine the viewport into which the SVG user agent can render
// the document. In some circumstances, SVG content will be embedded (by reference or inline) within a containing document.
// This containing document might include attributes, properties and/or other parameters (explicit or implicit) which specify
// or provide hints about the dimensions of the viewport for the SVG content. SVG content itself optionally can provide
// information about the appropriate viewport region for the content via the ‘width’ and ‘height’ XML attributes on the
// outermost svg element. The negotiation process uses any information provided by the containing document and the SVG
// content itself to choose the viewport location and size.
// The ‘width’ attribute on the outermost svg element establishes the viewport's width, unless the following conditions are met:
// * the SVG content is a separately stored resource that is embedded by reference (such as the ‘object’ element in XHTML [XHTML]),
// or the SVG content is embedded inline within a containing document;
// * and the referencing element or containing document is styled using CSS [CSS2] or XSL [XSL];
// * and there are CSS-compatible positioning properties ([CSS2], section 9.3) specified on the referencing element
// (e.g., the ‘object’ element) or on the containing document's outermost svg element that are sufficient to establish
// the width of the viewport.
//
// Under these conditions, the positioning properties establish the viewport's width.
