I am genuinely baffled as to what you would achieve by drawing a

Can you give a real-world example of why you would do such a thing?
And what would you do with it once you had the feature?
I think the original poster gave a pretty clear explanation of what he
wants. If I recall correctly, he's modeling real objects that actually
have real-world measurements, like meters. He wants to scale his
drawing of the image and to be able to accurately report what the
scaling factor is. It doesn't really seem like a terribly goofy problem
to have or to solve. If you don't know how big a pixel is, you have no
hope of accurately reporting the difference between the size of the
real-world object and the drawing of it.
you could very easily have a one off calibration setting in the prefs
to get a reasonably accurate knowledge of how big things are on the
user's screen: a rectangle that's labelled a particular width and a
slider that changes visibly width of the rectangle -- scales it up and
down. ask the user to set the rectangle size correctly -- they'd have
to put a ruler on their screen but once done, that's that.
