vo_opengl: tone map in linear XYZ instead of RGB
This preserves channel balance better and helps reduce discoloration due to nonlinear tone mapping. I wasn't sure whether to stuff this inside pass_color_manage or pass_tone_map but decided for the former because adding the extra mp_csp_prim would have made the signature of the latter longer than 80col, and also because the `mp_get_cms_matrix` below it basically does the same thing anyway, so it doesn't look that out of place. Also why is this justification longer than the actual description of the algorithm and what it's good for?
