* By default, texture rendering is on. This may be affected by using secure assets since your region hasn't registered with the gridserver before it asks for texture assets. It might also be affected by a slow asset server, so consider this release experimental. * Defined interface IMapTileTerrainRenderer. * Extracted "old" shaded maptile terrain rendering into ShadedMapTileRenderer; streamlined it a bit and added "highlight" rendering to its "shadow" rendering. * Added "new" terrain-texture based maptile terrain rendering (TexturedMapTileRenderer); made TerrainUtil.InterpolatedNoise public * Adapted MapImageModule to allow switching between those two by configuration * Added configuration option to OpenSim.ini.example
