Konq's KHTML is the only remaining web browser engine capable of rendering
physical sizes specified by legacy CSS accurately. The physical CSS units
cm, mm, in, etc. were changed in the CSS3 specification to be logical
sizes. When a display's physical density is matched to logical density by
the server, Konq displays physical units accurately at their actual
physical sizes. With other web browsers, this is only possible if the
physical display density is 96 DPI (uncommon to say the least) and the
server's default logical density of 96 DPI is retained.
Recent Gecko browsers do have the capability of rendering at accurate
physical sizes when physical and logical density match, but only by using
proprietary CSS which doesn't exist in legacy CSS.
http://fm.no-ip.com/Auth/dpi-screen-window.html is a simple means to
confirm the foregoing.
So maybe the old KHTML engine could be transformed into the "legacy mode"?
Maybe do as Konq 4 & 5 do, make it switchable.
Konq 4 offers KHTML and WebKit.
Konq 5 offers KHTML and (QT's) WebEnginePart (aka Blink, aka WebKit fork used by
Chromium). http://fm.no-ip.com/SS/KDE/konq5Engines.jpg
