/** \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
* 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
* 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 of pt: 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 to pt (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.
