In the PostScript standard, this lead to a model of the document as a program; a series of instructions to be executed by an interpreter which would result in ``ink'' being placed on ``pages'' of a fixed size\cite{plrm}. The ubiquitous Portable Document Format (PDF) standard provides many enhancements to PostScript taking into account desktop publishing requirements\cite{cheng2002portable}, but it is still fundamentally based on the same imaging model\cite{pdfref17}. This idea of a document as a static ``page'' has lead to limited precision in these and other traditional document formats. -Points to address: -\begin{enumerate} - \item What this is. - \item Why we should care - \item Most recent development - \item Do we really mean ``infinite''? (No. Sorry. We lied) - \item Foundational papers. Historical notes. -\end{enumerate} +The emergence of the internet, web browsers, XML/HTML, JavaScript and related technologies has seen a revolution in the ways in which information can be presented digitally, and the PDF standard itself has begun to move beyond static text and figures\cite{hayes2012pixels, barnes2013embedding}. However, the popular document formats are still designed with the intention of showing information at either a single, fixed level of detail, or a small range of levels. -See also: The Abstract. -See also: The Conclusion. +As most digital display devices are smaller than physical paper medium, all useful viewers are able to ``zoom'' to a subset of the document. Vector graphics formats including PostScript and PDF support rasterisation at different zoom levels\cite{plrm, pdfref17}, but the use of fixed precision floating point numbers causes problems due to imprecision either far from the origin, or at a high level of detail\cite{goldberg1991whatevery, goldberg1992thedesign}. -The remainder of this report will be organised as follows: Chapters \ref{BackgroundHardware} and \ref{BackgroundSoftware} will discuss approaches to representation of numbers in both Hardware and Software respectively; Chapter \ref{Approach} will outline the approach [reword] considering . Chapter/Appendices \ref{Implementation} will provide implementation notes. Chapter \ref{Results} will describe our results. Chapter \ref{Conclusion} will be the conclusion. +We are now seeing a widespread use of mobile computing devices with touch screens, where the display size is typically much smaller than paper pages and traditional computer monitors; it seems that there is much to be gained by breaking free of the restricted precision of traditional document formats. +\section{Overview} - -NOTE: Given that I don't actually need a full thesis, change from Chapters to Sections? -NOTE2: Will treat as a full thesis but if it gets too big, submit a condensed version as the MCTX "report". - -NOTE3: In final version, put the Approach at the end and/or in appendices before the Implementation notes rather than the start (?) +The remainder of this document will be organised as follows: In Chapter \ref{Proposal} we give an overview of the current state of the research in document formats, and the motivation for implementing ``infinite precision'' in a document format. We will outline our approach to research in collaboration with David Gow\cite{}. In Chapter \ref{Background} we provide more detailed background examining the literature related to rendering, interpreting, and creating document formats, as well as possible techniques for increased and possibly infinite precision. In Chapter \ref{Progress} gives the current state of our research and the progress towards the goals outlined in Chapter \ref{Introduction}. In Chapter \ref{Conclusion} we will conclude with a summary of our findings and goals.
