	)

Update tone equalizer sliders from one picker sample.

Tone equalizer exposes picker-enabled bauhaus sliders for exposure and contrast compensation. The sample is taken from the module input cache, so the picked luminance is measured before tone equalizer applies its own mask remapping. This keeps the call chain identical to filmicrgb: picker activation comes from the slider quad, sampling arrives through the shared picker proxy, and the callback commits the resulting parameter directly back into the GUI slider.

Blend and mask pickers dispatch through the same hook, therefore only the two tone equalizer slider widgets are handled here and every other picker falls through untouched.

Parameters

self	Current module instance.
picker	Active picker widget dispatched by the picker proxy.
pipe	Preview pipe that was sampled.
piece	Live pipe piece matching the sampled cacheline.
