Hammer of Thyrion is a cross-platform port of Ravens Hexen II source. It is based on an older linux port, Anvil of Thyrion.
HoT includes many bug fixes, opengl improvements, improved sound and video modes, and documentation among many others.
NOTE: Hexen II source, and the Hammer of Thyrion source port, are free
but the game itself is not: you must have an original copy of the
game released by Raven Software and Activision.

Main features:
- Support for Hexen II, Hexen II demo, Portal of Praevus mission pack and HexenWorld.
- Cross-platform code: Tested on Mac OS X, Linux, FreeBSD, OpenBSD, and Windows. The software renderer version is tested on QNX. Other unices should also work. There are seperate ports to MorphOS and PalmOS.
- Tested on 32 bit and 64 bit platforms.
- In-game resolution changing for both opengl and software renderers. Instant fullscreen/windowed toggling on X11 (unix).
- OpenGL enhancements including multitexturing, glow effects, working brightness control, text and hud size changing on the fly, translucent console background, console background stretching, colored lights and support for external lit files, fixes for texture cache and model mesh cache mismatches.
- Fully network-compatible with Ravens 1.11 windows version as well as with other Hexen II ports. Can load and play games saved with Ravens 1.11 windows version.
- The same binary handles both original hexen2 and the mission pack.
- The same hexen2 binary transparently handles both v1.11 (hexen2) and v1.12 (mission pack) style progs.dat files.
- Fullscreen intermissions and help dialogs.
- MouseWheel support.
- Improvements and fixes to the HexenC game code.
- Improved sound support: A selection of three different sound drivers (ALSA, OSS and SDL) for Linux. FreeBSD is supported with OSS and SDL, OpenBSD and NetBSD are experimentally supported with sunaudio and SDL.
- Working music volume controls and on the fly selection of CD or MIDI music.
- Full user directories support under unix: all users have their own configuration files and game saves.
- Improved console functionality (inline editing and tab completion), and a maplist command.
- Ability to delete saved games from within the game.
- Several hexen2 utilities (hcc: the hexenc compiler, and other mapping tools) are maintained and are being kept up to date.
- Several hexenworld utilities (hwmaster: hexenworld master server, hwmquery: tool for querying hw master servers, hwrcon and hwterm: rcon tools) are maintained and are being kept up to date.

Enhancements
- bumped the hexen2 engine version to 1.22, and hexenworld engine version to 0.22.
- fixed the broken software renderer binaries from C++ compilers with x86 assembly enabled (do not use the bool keyword of C++).
- compilations using the gcc-4.4 development versions were tested.
- added support for Microsoft Visual Studio 2008.
- added support for 64 bit windows versions (x64) using mingw-w64.
- opengl: fixed an issue that changing resolution from within the game might crash on Windows Vista.
- stricter checking on the values pulled out of .wav file chunk headers.
- renamed model_t to qmodel_t in order to avoid conflicts on solaris.
- fixed the "mirrored prints" problem of hexen2 console at high resolutions.
- fixed the colored prints of hexenworld console.
- fixed array going out-of-bounds (utils/map.c) and bogus maybe used uninitialized warnings (sbar.c) from gcc-4.3.
- fixes to the SVGALib driver. it is functional now.
- fixed bug #2176384: in windowed mode, when you save using the menus, the game used to quit the menu without grabbing the mouse properly.
- increased the buffersize for sdl audio. made it to print a little more detailed info at startup.
- launcher, patching: rewritten the inter-threads log printing and fixed the erratic crashes on smp systems. launcher version is 1.0.4 now.
- hexenworld master server: unknown packets are properly output as hexdump. hwmaster version is 1.2.6 now.
- other minor fixes.
- 3dfx gamma hacks are disabled by default at compile time (see the Makefile).
- killed compatibility with user directories from HoT-1.4.0 and earlier which didnt operate with a data1 subdirectory. they are ancient history now.
- added initial support for standalone free contents (mods) as an extra patch.
- added extra testing code to support midi when using sdl audio (extra patch).
- utils, qbsp: accept more than one wad file specified in the value of the "wad" key. the wad file names must be separated by a semicolon. spaces are allowed in the file names. quoted paths arent allowed.
- utils, qbsp: the absolute paths in wad values are not touched, ie. the paths beginning with a / on unix or with a drive specifying string like "C:foo ar.wad" on windows. all other values with no path information or relative path information are prefixed with the project path. this fixes the issues reported for qbsp usage from within worldcraft.
- added back some unused code for future reference. removed some truly dead code.
- minor documentation tidy-ups.

GIMP 2.6.6 brings you a dream tool for photo retouching, image composition, and image authoring. It is a powerful piece of software with capabilities not found in any other free software product. It can be used as a simple paint program, an expert-quality photo-retouching program, an online batch-processing system, a mass production image renderer, or an image-format converter. GIMP is modular, expandable, and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image-manipulation procedures to be easily scripted.

Major Features:

1. Customizable Interface
   • Each task requires a different environment and GIMP allows you to customize the view and behavior the way you like it. Starting from the widget theme, allowing you to change colors, widget spacings and icon sizes to custom tool sets in the toolbox. The interface is modulized into so called docks, allowing you to stack them into tabs or keep them open in their own window. Pressing the tab key will toggle them hidden.
   • GIMP features a great fullscreen mode allowing you to not only preview your artwork but also do editing work while using the most of your screen estate.
2. Photo Enhancement
   • Numerous digital photo imperfections can be easily compensated for using GIMP. Fix perspective distortion caused by lens tilt simply choosing the corrective mode in the transform tools. Eliminate lens' barrel distortion and vignetting with a powerful filter but a simple interface.
3. Digital Retouching
   • GIMP is ideal for advanced photo retouching techniques. Get rid of unneeded details using the clone tool, or touch up minor details easily with the new healing tool. With the perspective clone tool, it's not difficult to clone objects with perspective in mind just as easily as with the orthogonal clone.
4. Hardware Support
   • GIMP includes a very unique support for various input devices out of the box. Pressure and tilt sensitive tablets, but also a wide range of USB or MIDI controllers. You can bind often-used actions to device events such as rotating a USB wheel or moving a MIDI controller's slider. Change the size, angle or opacity of a brush while you paint, bind your favorite scripts to buttons. Speed up your workflow!
5. File Formats
   • The file format support ranges from the common likes of JPEG (JFIF), GIF, PNG, TIFF to special use formats such as the multi-resolution and multi-color-depth Windows icon files. The architecture allows to extend GIMP's format capabilities with a plug-in. You can find some rare format support in the GIMP plugin registry.

Enhancements:

• GIMP 2.6.6 is a bug-fix release in the stable GIMP 2.6 series. This release contains an important fix for compiling GIMP against the recently released GTK+ 2.16.
  

Requirements:

• GNU/Linux (i386, PPC)
• Microsoft Windows (XP, Vista)
• Mac OS X
• Sun OpenSolaris
• FreeBSD

Asymptote is a powerful descriptive vector graphics language that provides a natural coordinate-based framework for technical drawing. Labels and equations are typeset with LaTeX, for high-quality PostScript output.
A major advantage of Asymptote over other graphics packages is that it is a programming language, nor just a graphics program.

Main features:>
- provides a portable standard for typesetting mathematical figures, just as TeX/LaTeX has become the standard for typesetting equations.
- inspired by MetaPost, with a much cleaner, powerful C++-like programming syntax and floating-point numerics;
- runs on all major platforms (UNIX, MacOS, Microsoft Windows);
- mathematically oriented (e.g. rotation of vectors by complex multiplication);
- LaTeX typesetting of labels (for document consistency);
- uses simplex method and deferred drawing to solve overall size constraint issues between fixed-sized objects (labels and arrowheads) and objects that should scale with figure size;
- fully generalizes MetaPost path construction algorithms to three dimensions;
- compiles commands into virtual machine code for speed without sacrificing portability;
- high-level graphics commands are implemented in the Asymptote language itself, allowing them to be easily tailored to specific applications.

Enhancements:
- Full interactive 3D support has been added to Asymptote, with the option ofgenerating and embedding 3D PRC data in PDF files or rendering scenesdirectly with Asymptotes own fast OpenGL-based renderer. The implicitcasts from 3D to 2D objects were removed (in favour of call explicit callsto project). A path[][] texpath(string s) routine was added to convertstring into the paths that TeX would fill. Add boolean stroke parameter wasadded for shading (and clipping to) stroked paths. The Circle and Arcroutines were fixed. Autoscaling of graph axes limits is now disabled bydefault. A path3 path3(path p, triple plane(pair)=XYplane) constructor wasadded; the path3 routines were moved to C++ code. Optimized and robustversions of the intersection, windingnumber, inside, and surface extremaroutines were implemented. The lighting routines were replaced by theOpenGL model. Each Asymptote process once again uses a separatecurrentpen. A segmentation fault and an incorrect parameter in theDelaunay triangulation routine were fixed. This major overhaul of thethree-dimensional graphics has necessitated a few backwardsincompatibilities.
