Re: [udig-dev] uDig Scale Bar - Bug 1993

[Emily Gouge <egouge@xxxxxxxxxxxxxxx>]

I created a pull request against the main branch.
https://github.com/uDig/udig-platform/pull/170

I did not create a pull request against the locationtech_ip branch as 
there seems to be a bunch of changes that need to be applied to that 
branch and I am not sure how you want to merge those changes.
