But I propose a technique and you Erik - fgfs maitainer, so you can decide where to put this classes I think this shader method have advantages that shaders are in text files that can be changed by users without compiling all simgear and flightgear sources. This framework add you functionality to optimize shaders to you current architecture (NV/ATI or other machines) so we have higher framerates. because you can specify shaders that can be loaded to NV only or ATI only and during fgfs startup we can detect archtecture and load proper shader. for example using NV shaders on NV hardware can get 20% boost to framerate. and detection of hardware is so easy you can only querry about NV_fragment_program extension - so you have NV hardware overwise -ATI or other videocard. But I don't know about SGI - does this architecture support shaders at all? So I think that if you add new classes to simgear people can start using them and mekes things better.
