That's sort of correct, but not quite. We don't require OpenGL 4 for shader
model 4, see shader_glsl_get_caps() in wined3d for details. The main thing
that's blocking SM4 on Mesa is ARB_geometry_shader4 / GLSL 1.50. The latter in
particular is only available on core contexts in Mesa. Matteo is working on
making wined3d support those, at which point the requirement would become
something like OpenGL 3.2 or 3.3. You can hack shader_glsl_get_caps() to set
"shader_model" to 4 and it will sort of work, provided you don't try to use
geometry shaders.
