* FogCoord are supported, along with secondary color
* An ES2 context should be usable (useful for SDL2)

* glxgears works, but FlatShade is not implemented (and will probably never be), so it's slightly different then using GLES1.1 or actual GL hardware
* GL_TEXTURE_1D, GL_TEXTURE_3D and GL_TEXTURE_RECTANGLE_ARB are not yet supported in shaders (they are supported in fixed pipeline functions), and texture 3D are just a single 2D layer for now.
* Program that link only a GL_FRAGMENT or GL_VERTEX shader are not supported yet.
