Re: [PATCH] Measurement tool for GAL


Hi Nick,

That's because the label formatting just uses a fixed 2 DP display for
mm (it uses 4 for inches, and 1 for degrees). It's not a perfect
solution, but it does line up nicely when the labels are on the left
of the line. Stripping trailing zeroes would make it ragged when you
zoom in a bit and get "1, 1.25, 1.5, 1.75, 2".
