41// CSS specification offer following guidance on dealing with pixel sizes
42// when printing at
43// http://www.w3.org/TR/2004/CR-CSS21-20040225/syndata.html#length-units:
44//
45// Pixel units are relative to the resolution of the viewing device, i.e.,
46// most often a computer display. If the pixel density of the output
47// device is very different from that of a typical computer display, the
48// user agent should rescale pixel values. It is recommended that the [
49// reference pixel] be the visual angle of one pixel on a device with a
50// pixel density of 96dpi and a distance from the reader of an arm's
51// length. For a nominal arm's length of 28 inches, the visual angle is
52// therefore about 0.0213 degrees.
53//
54// For reading at arm's length, 1px thus corresponds to about 0.26 mm
55// (1/96 inch). When printed on a laser printer, meant for reading at a
56// little less than arm's length (55 cm, 21 inches), 1px is about 0.20 mm.
57// On a 300 dots-per-inch (dpi) printer, that may be rounded up to 3 dots
58// (0.25 mm); on a 600 dpi printer, it can be rounded to 5 dots.
59//
