Please be quick to suspect this commit if the build should break on Windows/MSVC.
(Again, sorry for the large commit, but I didnt want to flood the commit log with my git-style tiny commits.)

- FIX build error on vc8/release-noboost x64, ConvertUTF.c had wrong PCH settings.
- ADD knowext and listext verbs to assimp_cmd, add some raw docs.

Fixed some minor material bugs in NFF.

AC: A new AC test model (light + scaled texture)
IRR: Skybox, Assimp output consisting of 6 meshes and 6 textures + further test models (multi-instancing test + simple sphere and box). They are not working yet.

- further work on the collada loader. Should load static geometry correctly now, but still not properly integrated
- added some Collada sample files. The license is hopefully fine with this.
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@245 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
3DS: Fixed transformation problems (Pivot points), added WIP animation support. No target animation yet (cameras, spot lights). Not yet fully tested, but static models that worked before should still work now, except all look correct now :-) (some problems with very large models remaining)
Further work on the IRR and IRRMESH loaders. IRR still WIP, IRRMESH more stable now.
Work on the LWo loader. Added support for the "one-layer-only" mode. Hierarchy bug still unfixed, UV coords bug still unfixed.
Further work on the FindInvalidDataprocess. Improved validation for normals, no false positives anymore.
Further work on the MDR loader, still WIP.
Moved DeterminePType-Step to ScenePreprocessor.
aiAnimation::mDuration is optional now, ScenePreprocessor computes it automatically if set to -1.
Fixes in the SMD loader. Still crashes on some files.
Updated animation documentation.
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@236 67173fc5-114c-0410-ac8e-9d2fd5bffc1f

git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@218 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Fixed normal vector handling in the ASE loader. Improved animation & camera & light support - as for the 3DS Loader, still in the works.
Fixed AC - Loader. It is now able to load models with complex hierarchies correctly. Added a small workaround for Quick3D, which writes invalid AC files.
DXF-Loader skips {...} blocks produced by 3DS Max & AutoCad correctly now.
DefaultLogger doesn't repeat identical log messages now.
FindInvalidData-Process removes empty or dummy animation tracks now.
LWO-Loader recognizes complex shaders (such as Fresnel) correctly now. Other LLWO bugs still unsolved.
Fixed bugs in the Ply parser, causing non-triangular faces to crash.
Added some additional helperutilities to StreamReader.
Fixed a bug in ProcessHelper.h causing SPlitLargeMeses and SortBxPType to crash for meshes containing many bones.
Changed OB default material from black to gray.
Added additional test fils: ply (bugfix), ase (animation), QUick3D & Irr (in the works), STL (export from 3DS Max)
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@210 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Fixed a bug that caused the viewer to render "random" polygons in some special cases.
ASE: Added parsing support for *GROUP nodes. Improved light & camera handling (still WIP). Fixed a bug that was caused by a recent change. Improved logging.
Updated PretransformVertices. The step works now (and supports line and point meshes). Important: The position of the step in the pipeline has changed. No unit test yet.
Minor fixes to SortByPType. Added a config option that allows users to specify which primitive types they don't need.
Added WIP version of an Irrlicht Scene Loader (.irr).
Added a small helper class ("BatchLoader") to make it easy for loaders to load subsequent meshes from external files (needed for irr and lws).
Added test models for IRR. Added dwarf.x from the Irrlicht repository (readme included) to the test X files.
[Current TODO: Fix bugs in: AC, 3DS, LWO. Finish MDR and OG. Implement: IRR, LWS. Write some more ut's ... ]
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@197 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Moved the code to find degenerated primitives to a separate step that is not anymore active by default.
The FindInvalidData-Step isn't active by default now. It hast a flag and must be explicitly requested.
Added line and point handling code to the CalcTangentsStep - not yet tested.
Added support for the Sense 8 (WorldToolKit) NFF file format. The format uses the same file extension as the "Neutral File Format" (and is implemented in the same loader). Seems to work well, added test files for it.
Added itoa10 function - so we have itoa on all platforms.
Small optimizations in the SortByPType step.
Fixed the material validation: textured meshes without uv coords cause a warning now.
Fixed a minor isses with the OFF loader.
Added empty unit tests for the new steps - to be filled in the next days.
Added SceneCombiner.cpp. It contains utilities to join meshes and scenes. The latter will be needed by the LWS loader (LWS files contain references to external LWO files and the LWO loader is already to complicated that it would make sense to add an additional code path to it). Mesh joining is needed by some pp steps, but the code has not yet been moved to its new location.
Added WIP light & camera support to the ASE loader. Works for the moment, but there's much missing. ASE parser refactored, the code is still quite long but at least cleaner. Fixed a bug that caused ASE to import invalid texture coordinates.
Makefiles and VC8 solution are up-to-date. The rest isn't.
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@192 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
Added Cube.off, an off files that contains more than 3 idxs per face. It crashes at the moment, but my current revision here is able to load it.
git-svn-id: https://assimp.svn.sourceforge.net/svnroot/assimp/trunk@184 67173fc5-114c-0410-ac8e-9d2fd5bffc1f
