    renderer: implement new peak detection · 10670ff8

    This also allows us to finally separate peak detection from color
    management. The current place in the code actually has almost no
    drawbacks, since it's effectively free unless FBOs are disabled.
    
    One annoying consequence is that this means we will now always perform
    peak detection at the source resolution, even if the display is smaller.
    In the relatively common case of 4K video on 1080p displays, this is a
    performance regression. To fix it, we could try investigating whether to
    do the analysis after up/downscaling, but then we have more special
    cases to think about, so I think I'll live with the status quo for now.
    Peak detection isn't the end of the world even at 4K.
    
    Closes #40.
