 * Website: http://sourceforge.net/projects/simplehtmldom/
 * Additional projects: http://sourceforge.net/projects/debugobject/
 * Acknowledge: Jose Solorzano (https://sourceforge.net/projects/php-html/)
 * Contributions by:
 *	 Yousuke Kumakura (Attribute filters)
 *	 Vadim Voituk (Negative indexes supports of "find" method)
 *	 Antcs (Constructor with automatically load contents either text or file/url)
 *
 * all affected sections have comments starting with "PaperG"
 *
 * Paperg - Added case insensitive testing of the value of the selector.
 *
 * Paperg - Added tag_start for the starting index of tags - NOTE: This works
 * but not accurately. This tag_start gets counted AFTER \r\n have been crushed
 * out, and after the remove_noice calls so it will not reflect the REAL
 * position of the tag in the source, it will almost always be smaller by some
 * amount. We use this to determine how far into the file the tag in question
 * is. This "percentage" will never be accurate as the $dom->size is the "real"
 * number of bytes the dom was created from. But for most purposes, it's a
 * really good estimation.
 *
 * Paperg - Added the forceTagsClosed to the dom constructor. Forcing tags
 * closed is great for malformed html, but it CAN lead to parsing errors.
 *
 * Allow the user to tell us how much they trust the html.
 *
 * Paperg add the text and plaintext to the selectors for the find syntax.
 * plaintext implies text in the innertext of a node.  text implies that the
 * tag is a text node. This allows for us to find tags based on the text they
 * contain.
 *
 * Create find_ancestor_tag to see if a tag is - at any level - inside of
 * another specific tag.
 *
 * Paperg: added parse_charset so that we know about the character set of
 * the source document. NOTE: If the user's system has a routine called
 * get_last_retrieve_url_contents_content_type availalbe, we will assume it's
 * returning the content-type header from the last transfer or curl_exec, and
 * we will parse that and use it in preference to any other method of charset
 * detection.
 *
 * Found infinite loop in the case of broken html in restore_noise. Rewrote to
 * protect from that.
 *
 * PaperG (John Schlick) Added get_display_size for "IMG" tags.
