/**
* Dompdf - PHP5 HTML to PDF renderer
*
* Dompdf loads HTML and does its best to render it as a PDF. It gets its
* name from the new DomDocument PHP5 extension. Source HTML is first
* parsed by a DomDocument object. Dompdf takes the resulting DOM tree and
* attaches a {@link Frame} object to each node. {@link Frame} objects store
* positioning and layout information and each has a reference to a {@link
* Style} object.
*
* Style information is loaded and parsed (see {@link Stylesheet}) and is
* applied to the frames in the tree by using XPath. CSS selectors are
* converted into XPath queries, and the computed {@link Style} objects are
* applied to the {@link Frame}s.
*
* {@link Frame}s are then decorated (in the design pattern sense of the
* word) based on their CSS display property ({@link
* http://www.w3.org/TR/CSS21/visuren.html#propdef-display}).
* Frame_Decorators augment the basic {@link Frame} class by adding
* additional properties and methods specific to the particular type of
* {@link Frame}. For example, in the CSS layout model, block frames
* (display: block;) contain line boxes that are usually filled with text or
* other inline frames. The Block therefore adds a $lines
* property as well as methods to add {@link Frame}s to lines and to add
* additional lines. {@link Frame}s also are attached to specific
* AbstractPositioner and {@link AbstractFrameReflower} objects that contain the
* positioining and layout algorithm for a specific type of frame,
* respectively. This is an application of the Strategy pattern.
*
* Layout, or reflow, proceeds recursively (post-order) starting at the root
* of the document. Space constraints (containing block width & height) are
* pushed down, and resolved positions and sizes bubble up. Thus, every
* {@link Frame} in the document tree is traversed once (except for tables
* which use a two-pass layout algorithm). If you are interested in the
* details, see the reflow() method of the Reflower classes.
*
* Rendering is relatively straightforward once layout is complete. {@link
* Frame}s are rendered using an adapted {@link Cpdf} class, originally
* written by Wayne Munro, http://www.ros.co.nz/pdf/. (Some performance
* related changes have been made to the original {@link Cpdf} class, and
* the {@link Dompdf\Adapter\CPDF} class provides a simple, stateless interface to
* PDF generation.) PDFLib support has now also been added, via the {@link
* Dompdf\Adapter\PDFLib}.
