When reading the STL header for a "COLOR=rgb" part, the bytes were treated as signed chars, when in fact they can range from 0-255. This meant that any value greater than 127 would overflow, leading to an incorrect colour.
This change fixes the issue by treating the header as unsigned chars.
For consistency, use a light gray default diffuse color for STL files.
This provides consistency with other geometric types, like PLY, that use a
light-gray default material.
The text "solid" is the general STL header indicator that the file is in fact
an ascii STL archive. Allows spaces to precede the "solid" keyword, providing
compatibility with exporters that insert such (non-compliant )spaces.
Previously, the STL loader relied on a string check at the start of the
buffer to determine if the STL file was of ASCII representation. This led to
certain false-positives for binary STL files with the magic string present in
their header. This patch addresses the issue by adding a proper binary check
to the representation detection.
- pull in IOhannes' patch to set the gcc default visibility for all symbols to NO and to mark ASSIMP_API with __attribute__ ((visibility("default"))).
- drop unneeded ASSIMP_API from most internal classes in /code, we just need to keep some exports on Windows to keep AssimpView alive.

- 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.
- Update unit tests to reflect these changes. Currently I keep getting failures in some tests, this needs to be resolved *urgently*.

IrrXML receives memmapped UTF-8 input data now, it's own (faulty) conversion is not used anymore.
aiString's are explicitly UTF-8 now.
Slight refactorings and improvements.
Adding UTF-8/UTF-16 text files for ASE,obj,collada,ac3d. These contain various japanese/chinese character sequences.
Changing assimp_view's node view to display UTF-8 multibyte sequences correctly.

- Added format auto-detection to most loaders
- Simplified BaseImporter::CanRead() with some utility methods
- improved fast_atof -> no overruns anymore. Fuck you, irrlicht.
- added assimp_cmd tool to allow command line model processing. 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.
STL
- fixing a log warning which appears for every model
- added binary&ascii test spider, exported from truespace
MD3
- Cleaning up output tags for automatically joined player models.
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.
RemoveRedundantMaterials
- Added config option to specify a list of materials which are kept in every case.
UNREAL
- Added support for the old unreal data format (*.a,*.d,*.uc)
- tested only with exports from Milkshape
- more Unreal stuff to come soon

Added a working makefile for mingw, provides more configs now. Not perfect yet.
Added decompression part of zlib (inflate).
Moved IrrXML to ./contrib dir.
Moved some IRR/IRRmesh shared code.
FIXME: makefile for gnu/linux is untested yet.
Code cleanup.
Unified #ifndef ASSIMP_BUILD_nnn_IMPORTER directives.
OBJ loader supports map_bump, map_ka, map_ks, map_ns now.
Endianess conversion in the ply loader is correct now.
Changed IRR/IRRMESH coordinate system conversion. Not absolutely right now, but better than before.

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)

Added AC-loader, WIP version.
PLY loader is now able to load models from blender, test model added. Refactoring.
Added FindInvalidData step.
Added support for precompiled headers, the release builds in VC8 are configued to use PCH now.
Added separate makefile for mingw, no -FPic warning anymore, -clear works now.
