Re: [AD] GLSL #version

I think I'd prefer that over a "magic main" type macro, but that's just my
vote.

Thanks,

This is essentially the solution used with OpenGL. It'd look something 
like this:

al_attach_shader_source_file(ALLEGRO_SHADER *shader, ALLEGRO_SHADER_TYPE 
type, const char *prefix, const char *filename);

I suppose that is one solution.

I looked briefly into auto-detecting the GLSL version at runtime and 
just sticking it in if it wasn't there already, but the way you'd do it 
requires parsing compiler-dependent strings which is too brittle, I think.
