CSS selector case insensitivity in HTML not honoured

Element name CSS selectors in HTML are case insensitive, i.e. SPaN matches <span>. This behaviour is currently not guaranteed by rasterizeHTML.js as the input is transformed to XHTML where selectors are case sensitive.

Additionally it should be checked whether the same applies to the :hover and :active selector rewrites.

    There doesn't seem to be a clean way of knowing whether a CSS tag name selector references an HTML tag or one of another namespace (e.g. svg).

    Idee: Scan the element tree for HTML and non-HTML tags. Then in unambiguous cases (e.g. td only found in HTML NS parts of the DOM) convert matching HTML tag name selectors to lowercase.
