* More of the OpenJPEG decoding functions spit out image info (so you can tell if an image contains alpha)
* Added an indexer property to InternalDictionary
* TerrainManager stores sim heightmaps with an InternalDictionary now
* Added an LLColor helper constructor for inversed alpha only
* Switched TextureEntry decoding to use the inversed LLColor decoder (was apparently backwards before)
[primpreview]
* Added two-pass rendering. Kind of klunky, but fixes enough of the alpha sorting problems to make the app usable again
