[Texmacs-dev] line_breaker_rep question

[skhilji]

I noticed that in several places when we pass penalty values based on length 
differences to line_breaker_rep::test_better() function, we divide it by PIXEL 
first.

For example,

square(d/PIXEL)
square((spc->min-line_width)/PIXEL)

Why are we doing this?

Based on what I know, if you have, for example, a length of 1.0 inches, then 
TeXmacs works with values that are

1.0 * dpi * PIXEL = <TexMacs Values>

So if we divide a length by PIXEL, we get the value in inches multiplied by 
dpi. It is somewhat confusing for me to come up with an explanation as to why 
we are dividing by PIXEL in every case.
