+ /** \note
+ * The ISO page sizes in the table below differ from ghostscript's idea of page sizes (by
+ * less than 1pt). Being off by <1pt should be OK for most purposes, but may cause fuzziness
+ * (antialiasing) problems when printing to 72dpi or 144dpi printers or bitmap files due to
+ * postscript's different coordinate system (y=0 meaning bottom of page in postscript and top
+ * of page in SVG). I haven't looked into whether this does in fact cause fuzziness, I merely
+ * note the possibility. Rounding done by extension/internal/ps.cpp (e.g. floor/ceil calls)
+ * will also affect whether fuzziness occurs.
+ *
+ * The remainder of this comment discusses the origin of the numbers used for ISO page sizes in
+ * this table and in ghostscript.
+ *
+ * The versions here, in mm, are the official sizes according to
+ * <a href="http://en.wikipedia.org/wiki/Paper_sizes">http://en.wikipedia.org/wiki/Paper_sizes</a>
+ * at 2005-01-25. (The ISO entries in the below table
+ * were produced mechanically from the table on that page.)
+ *
+ * (The rule seems to be that A0, B0, ..., D0. sizes are rounded to the nearest number of mm
+ * from the "theoretical size" (i.e. 1000 * sqrt(2) or pow(2.0, .25) or the like), whereas
+ * going from e.g. A0 to A1 always take the floor of halving -- which by chance coincides
+ * exactly with flooring the "theoretical size" for n != 0 instead of the rounding to nearest
+ * done for n==0.)
+ *
+ * Ghostscript paper sizes are given in gs_statd.ps according to gs(1). gs_statd.ps always
+ * uses an integer number ofpt: sometimes gs_statd.ps rounds to nearest (e.g. a1), sometimes
+ * floors (e.g. a10), sometimes ceils (e.g. a8).
+ *
+ * I'm not sure how ghostscript's gs_statd.ps was calculated: it isn't just rounding the
+ * "theoretical size" of each page topt (see a0), nor is it rounding the a0 size times an
+ * appropriate power of two (see a1). Possibly it was prepared manually, with a human applying
+ * inconsistent rounding rules when converting from mm to pt.
+ */
+ /** \todo
+ * Should we include the JIS B series (used in Japan)
+ * (JIS B0 is sometimes called JB0, and similarly for JB1 etc)?
+ * Should we exclude B7--B10 and A7--10 to make the list smaller ?
+ * Should we include any of the ISO C, D and E series (see below) ?

+ /* See http://www.hbp.com/content/PCR_envelopes.cfm for a much larger list of US envelope
+ sizes. */
+ /* Note that `Folio' (used in QPrinter/KPrinter) is deliberately absent from this list, as it
+ means different sizes to different people: different people may expect the width to be
+ either 8, 8.25 or 8.5 inches, and the height to be either 13 or 13.5 inches, even
+ restricting our interpretation to foolscap folio. If you wish to introduce a folio-like
+ page size to the list, then please consider using a name more specific than just `Folio' or
+ `Foolscap Folio'. */
