Subject: Handle SelectionOutline interface implementation in SCLScenegraph
X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=f48fa9bd04b1802047c1eba99ad73eb4234a46c2;p=simantics%2Fplatform.git

Handle SelectionOutline interface implementation in SCLScenegraph

Created custom SelectionShapeNode class for outline highlights, so that
SCLScenegraph can process outline as selection.

(cherry picked from commit 37c78d83578e57c8bb858d51591446994405b617)
