Yes, that's the only way that will work. The shader backend mutually talks to 
opengl, we have to design it around the requirements of the opengl 
(extension) APIs. Trying to stick the shader backend's design to d3d will not 
work properly

All in all we can only have a ffp replacement shader OR a d3d shader active. 
Some instance has to sort out what is active, and given that in GLSL we'll 
need to link vertex+fragment+geometry shaders the shader backend is the best 
place to find that out IMHO
