Remarks

This section contains detailed documentation for members that don't have a source file. It reduces clutter in the main section of the header.

Polygon references are subject to the same invalidate/preserve/restore rules that apply to dtTileRef's. If the dtTileRef for the polygon's tile changes, the polygon reference becomes invalid.

Changing a polygon's flags, area id, etc. does not impact its polygon reference.
