Work in progress minimap. Known issues:
- "path finding" doesn't appear to work - it gets stuck forever in many
cases
- some nasty patches around timer-based code
- jak arrow blending issues
- would be nice to make it higher resolution
if the search is forced to terminate due to iteration/time limits, the
icon is not in the right place
