Attempting to improve the robustness of texture decoding by always ignoring LayerInfo.End values and creating guessed default layer boundaries on failed decodes Changed a noisy J2K decode log message from Info to Debug Replacing openjpeg-dotnet decoding with managed CSJ2K decoding. Should be much more reliable, faster, and use less memory

Browse Source 
* Re-added openjpeg-dotnet files since they are used elsewhere in OpenSim * Updated prebuild.xml with a reference to CSJ2K

* Renamed IJ2KDecoder and J2KDecoder member names to follow standard naming conventions * Removed j2kDecodeCache cruft and replaced it with the OpenSim cache system * Rewrote the default layer boundary algorithm to use percentages instead of an exponent * Switched from an infinite in-memory cache to an expiring cache (10 minute timeout) * Slightly quieted logging errors for failed texture decodes
