I removed the info because I thought it was kind of obvious, but in
any case, it should probably go elsewhere.  Position, colors,
texcoords and generic attributes all behave that way.  We should
probably document this somewhere for vertex shaders in general.  Or,
document it with the vertex array / format information.
