big one

-Implemented configurable view limits on all axis. This can restrict user from moving camera outside a geographic sector
-Animation framework for camera position or object positions. Allows animated transition from perspective to overhead views, similar to the Trimble demo
-Per-frame statistics framework
-status bar showing network status and map position
-Configurable Layer opacity. Any layer can be rendered semi-transparently
-Geographic calculation functionality
-Debug rendering of bounding volumes
-Texture mip map loading
-Multitexture support
-Fixed perspective viewing frustrum to allow view to zoom in closer and render from lower altitudes.
-Fixed 2-finger scale gesture detector to allow smooth zooming into low altitudes
-Fixed view pitch rotation so that camera does not go underground in perspective views
-Implemented a configurable Horizon distance modifier, which can control how far into the horizon the imagery is rendered while in perspective view. 
-Implemented on-the-fly ETC1 Texture Compression support (with Alpha channel) when loading uncompressed imagery from datasource
-Implemented pre-compression of imagery data as it is downloaded from WorldWind data server. This saves the imagery to internal memory cache in ETC1 format (with Alpha channel) which saves storage space and loading time.
-Added automatic clocked-rendering mode in addition to the existing on-request rendering mode. Each frame is automatically scheduled using a configurable frame-rate. This results in smoother animation and position updates.
-surfaceshape and prerendering infrastructure
-pick frustruma.
