The linetype library is defined in inches, and LINETYPE loaded it
unchanged into metric drawings: DASHED was 0.5 mm on, 0.25 mm off at
LTSCALE 1, so dashed lines looked solid. CAD programs load ISO-scaled
definitions when MEASUREMENT is 1 (the same patterns with lengths times
25.4). library::standard_linetypes_for(d) does the equivalent with our
own definitions: in a metric drawing every length (dashes, gaps, text and
shape size, offsets) is scaled by 25.4 as it is loaded. LINETYPE and the
CENTER linetype that CENTERMARK/CENTERLINE load use it. Definitions
already in a drawing are not changed.
