Section 4.3.2 Lengths
[2001-08-28] The suggested reference pixel is based on a 96 dpi device, not 90 dpi. The
visual angle is thus about 0.0213 degrees instead of 0.0227, and a pixel at arm's
length is about 0.26 mm instead of 0.28
ahh... that might be interesting, although the proper fix is to get Inkscape properly
dynamic about DPI and remove all hardcodings.
I think the 90 DPI hardcodings came from SVG 1.0 timeframe... but only has recently been
removed enough to make full dynamic possible.
