* Noise, and Noise-Area brushes now use Perlin noise, more closely simulating the method LL uses officially.
* TerrainModule has been cleaned up slightly.
* TerrainUtil class has several new functions related to seeded noise generation.
* Extracted ITerrainEffect, ITerrainFloodEffect, ITerrainLoader, ITerrainPaintableEffect, TerrainChannel to seperate files.
* Terrain Area-of-Effect brushes now should work properly.
* Updated the scale / effect of various brushes. Small & Medium brushes should now actually do something.
* W.I.P: Hydraulic Erosion (Spherical) paintbrush - code is all there, but some work is required on the initial parameters to get it to function correctly. Replaces the smooth brush when `newbrushes` is switched on.
* Implements the Optimised Erosion routine defined by Jacob Olsen in the paper 'Procedural Terrain Generation' (http://www.oddlabs.com/download/terrain_generation.pdf)
* Replaces the 'flatten' brush when 'newbrushes' is enabled.
* Added "script terrain newbrushes <true|false>" to enable experimental terraforming brushes. Presently the 'revert' brush is replaced with the Weathering brush, when enabled.
Also added osSetDynamicTextureDataBlend and osSetDynamicTextureURLBlend that will allow the various textures to be blended together, but currently there are still a few bugs in them. So not ready for use yet.
* Enabled new TerrainModule. (The king is dead, long live the king!)
* Use the console command: "script terrain save file.r32" / "script terrain load file.r32" to load/save terrain. Now uses the extension to determine file format.
* MANY of the old terrain features do not have a replacement function in the new module yet, this needs to be corrected, but has not been done so far. This being said, the new module is faster and more efficient and should be a good replacement.
* *Much* faster terraforming (woot!)
* New "Brushes" design, so you can create custom terraforming brushes then apply those inplace of the standard tools. (ie an Erode Brush for example)
* New specialised "Flood Brushes" to do large area effects, ie, raise-area, now takes a bitmap rather than repeats the ordinary raise brush a thousand times.
* New modular file Load/Save systems -- write importers/exporters for multiple formats without having to hard code the whole thing in.
* Coming soon - effects system, ie the old Erosion functions, etc. for one-shot effects.
** Added more realistic calculations of mass for the rest of the supported prim shapes+holes+cuts+tapers. Previously they were the generic height * width * length. Spheres roll (Angular velocity) more realistically, etc.
So anyway, it moves the Asset downloading (packet sending) to a module (AssetDownloadModule).
So now at last, AssetCache should be just dealing with fetching assets from the asset server and caching them.
