1. ​ARB: assembly-like shading language, more widely supported than GLSL (esp. on older hardware)
2. ​GLSL: OpenGL Shading Language. Higher level, C-like language. Requires OpenGL 2.0 or newer.
3. ​Fixed function - pre-shader OpenGL API, now deprecated in favor of shaders. In 0 A.D., the fixed function pipeline will always be very basic compared to the shader rendering, and it may eventually be removed entirely. See discussion here.
4. ​OpenGL ES 2.0 - subset of OpenGL API for embedded systems, like smartphones and tablets. Very experimental, likely broken support is available in 0 A.D. by compiling with the --gles flag. Used by AndroidPort.
