/**
* Website: http://sourceforge.net/projects/simplehtmldom/
* 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.
