PAF Visual Enhancements

Suggested "visual enhancements" to PAF. As it'll be difficult to "decorate" PAF as a closed source project, these may not be feasible.
1. "Easy way" to see who were direct ancestors. When in tree view/ancestor view: which people are "direct" ancestors of the "current" person. Currently indicated via setting the name to all-caps for people on the direct line from "dad"; non-direct people are in lowercase.
2. Illustrate changes from state-to-state. In pedigree view, and family view. When a person's birth/death locations have changed across state lines.

No files or tests are named. Start by locating the tree view/ancestor view and the pedigree and family views, then assess whether the proposed visual changes fit the existing closed-source PAF behavior. Done would mean an agreed feasible design for distinguishing direct ancestors and showing birth/death location changes across state lines.
