+// CSS specification offer following guidance on dealing with pixel sizes
+// when printing at
+// http://www.w3.org/TR/2004/CR-CSS21-20040225/syndata.html#length-units:
+//
+//      Pixel units are relative to the resolution of the viewing device, i.e.,
+//      most often a computer display. If the pixel density of the output
+//      device is very different from that of a typical computer display, the
+//      user agent should rescale pixel values. It is recommended that the [
+//      reference pixel] be the visual angle of one pixel on a device with a
+//      pixel density of 96dpi and a distance from the reader of an arm's
+//      length. For a nominal arm's length of 28 inches, the visual angle is
+//      therefore about 0.0213 degrees.
+//
+//      For reading at arm's length, 1px thus corresponds to about 0.26 mm
+//      (1/96 inch). When printed on a laser printer, meant for reading at a
+//      little less than arm's length (55 cm, 21 inches), 1px is about 0.20 mm.
+//      On a 300 dots-per-inch (dpi) printer, that may be rounded up to 3 dots
+//      (0.25 mm); on a 600 dpi printer, it can be rounded to 5 dots.
+//
+// See also http://trac.wxwidgets.org/ticket/10942.
