ET-XreaL id Tech 3 Features:
    * Modern OpenGL 3.2 renderer with all deprecated OpenGL calls removed
    * Clever usage of vertex buffer objects (VBO) to speed up rendering of everything
    * Avoids geometry processing each frame using the CPU (worst bottleneck with the Q3A engine)
    * Renders up to 500 000 - 1 000 000 polygons at 80 - 200 fps on current hardware (DX10 generation)
    * Optional GPU occlusion culling (improved Coherent Hierarchy Culling) useful for rendering large city scenes
    * Doom 3 .MD5mesh/.MD5anim skeletal model and animation support
    * Unreal Actor X .PSK/.PSA skeletal model and animation support
    * True 64 bit HDR lighting with adaptive tone mapping
    * Advanced projective and omni-directional soft shadow mapping methods like EVSM
    * Real-time sun lights with parallel-split shadow maps
    * Optional deferred shading
    * Relief mapping that can be enabled by materials
    * Optional uniform lighting and shadowing model like in Doom 3 including globe mapping
    * Supports almost all Quake 3, Enemy Territory and Doom 3 material shader keywords
    * TGA, PNG, JPG and DDS format support for textures
    * Usage of frame buffer objects (FBO) to perform offscreen rendering effects
    * Improved TrueType font support that does not require external tools
    * Linux 64-bit support
    * Linux sound backend using SDL
    * .avi recorder from ioquake3 including sound support
    * Optimized collision detection routines
    * Support for Omni-bot

ET-XMap BSP Compiler Features:
    * Based on q3map2 by Randy 'ydnar' Reddig including additional fixes by the NetRadiant edition
    * Supports Doom 3 and Quake 4 .map formats
    * Built-in mini BSP viewer using -draw

Future Plan:
    * Add a Creative Commons BY-SA high resolution texture replacement pack including new material definitions to support diffuse, normal and specular textures
    * Create improved versions of existing maps with an etx_ prefix like:
       etx_beach
       etx_battery
       etx_fueldump
       ...
    * Add fake per pixel lighting to allow bump mapping if ETXreaL runs a map that has no deluxemaps
    * Improve ETXMap ET .map -> Doom 3 .map format conversion routine to handle spawnflags -> boolean type conversions
    * Improve ETXMap compiler for better support of extracting models from .bsp files for further editing in Blender or other 3D tools
    * Finish Doom 3 style DarkRadiant entity definitions file etmain/def/entities.def to have full support for all ET entity types
    * Add Blender tools to make it easier to replace the existing models
    * Optimize ET decal system with VBOs
    * Add Bullet physics engine (maybe)
