- The only difference from version 3.0 to version 3.1 is that the position
- of the "magnet" has been shifted by 14 fig units.
- In the 2.1 and older versions of xfig the grid was in multiples of 5 fig
- units, but they were on intervals 4, 9, 14, 19, etc.
- When version 3.0 was created, coordinates were simply multiplied by the
- ratio of the resolutions (1200/80 = 15) so values like 4 became 60 instead
- of 74 ((4+1)*15 - 1).
-
- This means that figures converted from 2.1 and older files are offset by
- 14 fig units but new objects entered with version 3.0 are correct.
-
- In version 3.1 the magnet grid is at intervals 0, 75, 150, etc instead of
- -1, 74, 149, etc.
- Figures from 2.1 and older are correctly converted now and a warning is popped
- up when you read in a version 3.0 file that says you may have to offset the
- figure when you load it, using the x and y offsets in the file panel.
