# Integrated Actor Viewer and Actor Editor tools

ObjectManager: Removed ObjectTypes because it hasn't been used for
years.
Atlas: Fixed leak when saving with Xerces. Changed range of water
shininess slider.
Actor Editor: Relabelled "Freq" to "Ratio". Made modal dialogs use the
correct parent.

This was SVN commit r4376.
