// Original description: (Schrompf)
// Adapted to the ASSIMP library because the builtin atof indeed takes AGES to parse a
// float inside a large string. Before parsing, it does a strlen on the given point.
// Changes:
// 22nd October 08 (Aramis_acg): Added temporary cast to double, added strtoul10_64
// to ensure long numbers are handled correctly

Fixed some minor issues in the AC loader. However, it still crashes with large and complicated models. Line handling is complete. 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

Mainly adebugging tool for internal purposes, but others might find it useful, too. - vc8/vc9: revision number is now written to DLL version header - mkutil: some batch scripts to simplify tagging & building of release versions - some API cleanup - fixing some doxygen markup (+now explicit use of @file <filename>) - Icon for assimp_view and assimp_cmd 3DS - Normal vectors are not anymore inverted in some cases - Improved pivot handling - Improved handling of x-flipped meshes Collada - fixed a minor bug (visual_scene element) LWS - WIP implementation. No animations yet, some bugs and crashes. - Animation system remains disabled, WIP code - many test files for LWS, but most of them test the anim support, which is, read above, currently disabled.

IRR - Fixing coordinate system issues. - Instance handling improved. - Some of the reported crashes not yet fixed. PretransformVertices - Numerous performance improvements. - Added config option to preserve the hierarchy during the step.

Fixed some minor issues in the AC loader. However, it still crashes with large and complicated models. Line handling is complete. 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

// NOTE: The original implementation is highly inaccurate here. The precision of a single
// IEEE 754 float is not high enough, everything behind the 6th digit tends to be more
// inaccurate than it would need to be. Casting to double seems to solve the problem.
// strtol_64 is used to prevent integer overflow.
// Another fix: this tends to become 0 for long numbers if we don't limit the maximum
// number of digits to be read. AI_FAST_ATOF_RELAVANT_DECIMALS can be a value between
// 1 and 15.
