vo_opengl: tone map on the maximum signal component
This actually makes sure we don't decolor due to clipping even when the signal itself exceeds the luma by a significant factor, which was pretty common for saturated blues (and to a lesser degree, reds) - most noticeable in skies etc. This prevents the turn-the-sky-cyan effect of mobius tone mapping, and should also improve the other tone mapping modes in quality.
