Link against pthreads library on systems that do not include it automatically. Fixes issue 149.

Plus for safeties sake use BeginThreadAffinity()...

+V.   Known Issues
+VI.  Frequently Asked Questions
+--------------------------------------------------------------------------------
+
+I.   Introduction
+--------------------------------------------------------------------------------
+
+This is our first alpha release of our new Texture Tools. The main highlights of 
+this release are support for all DX10 texture formats, higher speed and improved
+compression quality.
+
+In addition to that it also comes with a hardware accelerated compressor that 
+uses CUDA to compress blocks in parallel on the GPU and runs around 10 times 
+faster than the CPU counterpart.
+
+You can obtain CUDA from our developer site at:
+
+http://developer.nvidia.com/object/cuda.html
+
+The source code of the Texture Tools is being released under the terms of 
+the MIT license.
+
+
+II.  Contents
+--------------------------------------------------------------------------------
+
+This release contains only the source code of the texture compression library
+and an example commandline application that shows its use.
+
+
+III. Compilation Instructions
+--------------------------------------------------------------------------------
+
+The compression library and the example can be compiled with Visual Studio 8 on 
+Windows using the following solution file:
+
+project\vc8\nvtt.sln
+
+On most other platforms you can also use cmake. For more information about 
+cmake, visit:
+
+http://www.cmake.org/
+
+On unix systems you can use the standard build procedure (assuming cmake is 
+installed on your system):
+
+$ ./configure
+$ make
+$ sudo make install
+
+
+IV.  Using NVIDIA Texture Tools
+--------------------------------------------------------------------------------
+
+To use the NVIDIA Texture Tools in your own applications you just have to
+include the following header file:
+
+src/nvimage/nvtt/nvtt.h
+
+And include the nvtt library in your projects. 
+
+The following file contains a simple example that shows how to use the library:
+
+src/nvimage/nvtt/compress.cpp
+
+The usage of the commandline tool is the following:
+
+$ nvcompress [options] infile [outfile]
+
+where 'infile' is and TGA, PNG, PSD, DDS or JPG file, 'outfile' is a DDS file
+and 'options' is one or more of the following:
+
+Input options:
+  -color   	The input image is a color map (default).
+  -normal  	The input image is a normal map.
+  -tonormal	Convert input to normal map.
+  -clamp   	Clamp wrapping mode (default).
+  -repeat  	Repeat wrapping mode.
+  -nomips  	Disable mipmap generation.
+
+Compression options:
+  -fast    	Fast compression.
+  -nocuda  	Do not use cuda compressor.
+  -rgb     	RGBA format
+  -bc1     	BC1 format (DXT1)
+  -bc2     	BC2 format (DXT3)
+  -bc3     	BC3 format (DXT5)
+  -bc3n    	BC3 normal map format (DXT5n/RXGB)
+  -bc4     	BC4 format (ATI1)
+  -bc5     	BC5 format (3Dc/ATI2)
+
+In order to run the compiled example on a PC that doesn't have Microsoft Visual 
+Studio 2003 installed, you will have to install the Microsoft Visual Studio 2003
+redistributable package that you can download at:
+
+http://go.microsoft.com/fwlink/?linkid=65127&clcid=0x409
+
+
+V.   Known Issues
+--------------------------------------------------------------------------------
+
+None so far. Please send suggestions and bug reports to:
+
+TextureTools@nvidia.com
+
+or report them at:
+
+http://code.google.com/p/nvidia-texture-tools/issues/list
+
+
+VI.  Frequently Asked Questions
+--------------------------------------------------------------------------------
+
+- Do the NVIDIA Texture Tools work on OSX?
+It currently compiles and runs properly, but it has not been tested extensively.
+In particular there may be endiannes errors in the code.
+
+
+- Do the NVIDIA Texture Tools work on Linux?
+Yes.
+
+
+- Do the NVIDIA Texture Tools work on Vista?
+Yes, but note that CUDA is not supported on Vista yet, so the tool is not hardware 
+accelerated.
+
+
+- Is CUDA required?
+No. The Visual Studio solution file contains a configuration that allows you
+to compile the texture tools without CUDA support. The cmake scripts automatically
+detect the CUDA installation and use it only when available.
+
+
+- Where can I get CUDA?
+http://developer.nvidia.com/object/cuda.html
+
+
+- Why is feature XYZ not supported?
+In order to keep the code small and reduce maintenance costs we have limited the 
+features available in our new texture tools. We also have open sourced the code, so
+that people can modify it and add their own favourite features.
+
+
+- Can I use the NVIDIA Texture Tools in my commercial application?
+Yes, the NVIDIA Texture Tools are licensed under the MIT license.
+
+
+- Can I use the NVIDIA Texture Tools in my GPL application?
+Yes, the MIT license is compatible with the GPL and LGPL licenses.

-# NVTT is discontinued
-
-After more than 14 years maintaining and updating this library on my spare time, I've decided to officially discontinue it and focus my energy on other projects.
-
-When I released NVTT there was very little public information about compression for GPU texture formats. Existing codecs were closed-source, encumbered by patents, and not particularly efficient or high quality. A lot has changed since then. NVTT doesn't support the latest formats anymore, some of its codecs are outdated, and it's source code has aged. Today most IHVs maintain their own open source codecs and several companies develop high quality commercial products around texture compression. 
-
-If you are looking for alternative texture compression tools and processing algorithms I recommend you check these out:
-
-## Open Source Encoders
-
-* I still maintain [A High Quality SIMD BC1 Encoder](https://github.com/castano/icbc).
-* [rgbcx](https://github.com/richgel999/bc7enc/blob/master/rgbcx.h) is another high-performance (but scalar) BC1-5 encoder.
-* [stb_dxt](https://github.com/nothings/stb/blob/master/stb_dxt.h) is a single header library that provides low quality, but fast BC1-5 encoders.
-* [Binomial](https://www.binomial.info/) is an image and texture compression company that develops [Basis a universal texture codec](https://github.com/BinomialLLC/basis_universal) and also has [other open source codecs](https://github.com/BinomialLLC).
-* [Intel ISPC Texture Compressor](https://github.com/GameTechDev/ISPCTextureCompressor) is a set of set of open source SIMD texture encoders that are very fast, but low quality.
-* [AMD Compressonator](https://gpuopen.com/compressonator/) offers various open source encoders that also run on the GPU.
-* [Betsy](https://github.com/darksylinc/betsy/) is a compressor for various GPU formats using compute shaders.
-* For ETC encoders see Google's [Etc2Comp](https://github.com/google/etc2comp), Bartosz Taudul's [etcpak](https://github.com/wolfpld/etcpak) and Rich Geldreich's [rg-etc1](https://github.com/richgel999/rg-etc1).
-* [ARM ASTC Encoder](https://github.com/ARM-software/astc-encoder) is an excellent ASTC encoder.
-* This is [a good overview of the state of texture encoders in 2020](https://aras-p.info/blog/2020/12/08/Texture-Compression-in-2020/).
-
-## Image Processing and IO
-
-* [stb_image_resize](https://github.com/nothings/stb/blob/master/stb_image_resize.h) provides polyphase image resize filters that are similar to what NVTT supports.
-* [Dario Manesku's cube map filtering tool](https://github.com/dariomanesku/cmft) seems like a good alternative for the cube map filtering functions in NVTT.
-* [CubeMapGen](https://gpuopen.com/archived/cubemapgen/) is another source of information for cubemap filtering algorithms, but is now unsupported as well.
-* Deano Calver supports [three tiny libraries](https://deanoc.com/2019/09/tiny) that provide support for DDS and KTX file formats, and pixel format conversion.
-* [stb_image](https://github.com/nothings/stb/blob/master/stb_image.h) and [stb_image_write](https://github.com/nothings/stb/blob/master/stb_image_write.h) are two handy single header libraries to read and write images in various formats.
-* https://github.com/syoyo/tinyexr
-* https://lodev.org/lodepng/
-* [texturec](https://bkaradzic.github.io/bgfx/tools.html#texture-compiler-texturec) is a handy command line tool similar to `nvcompress`, built on top of [bimg](https://github.com/bkaradzic/bimg).
-* The venerable [ImageMagick](https://imagemagick.org/) still provides many valuable tools and utilities.
-
-## Commercial Libraries
-
-* [Oodle Texture](http://www.radgametools.com/oodletexture.htm) is a suite of commercial RDO texture codecs.
-* [NVIDIA Texture Tools exporter](https://developer.nvidia.com/nvidia-texture-tools-exporter) is based on a private fork of this project and offers additional GPU accelerated codecs, but it's not open source.
