Subject: Fixed District diagram viewer to allow moving of vertices again.
X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F55%2F4055%2F1;p=simantics%2Fdistrict.git

Fixed District diagram viewer to allow moving of vertices again.

The problem was caused by the default grid snap advisor which the base
DiagramViewer injects into the canvas context, which had 1.0mm snap
region. This removes the snap advisor entirely.

gitlab #82
