Gimp missing dependency on graphviz
When installing Gimp on OI 20201031 illumos-beed421eff there are no issues.
But running Gimp results in an error messages: GEGL:introspective is missing.
A 'truss gimp' reveals that it is in fact /usr/bin/dot that it's missing.
Installing pkg:/image/graphviz solves this.
So the dependency should be added to the Gimp package.
