I'm in the process of adding support for these NV assembly extensions.
I'm working on GL_NV_fragment_program_option now (see the
asm-shader-rework-2 branch). GL_NV_vertex_program2_option is next.
GL_NV_fragment_program2, which uses the signed saturation, will follow
shortly after that.
This is just a heads-up in case you're about to make design choices that
will make some of this stuff harder to add. :)
