installFastSliceRepaint ​

▸ installFastSliceRepaint(rawSlice, exposure?): Promise<void>

Idempotent: patching an already-patched slice is a no-op.

exposure is a gamma exponent, normally from exposureExponent(); 1 leaves greyscale exactly as the original produced it.

CALL THIS BEFORE THE FIRST PAINT. The LUT lives in the patched method, so painting first draws one un-lifted frame and corrects it on the reader's first scrub -- a visible colour change.

Async only because PlaneGeometry is imported on demand, to keep three out of a consumer's initial chunk when nothing scrubs a slice.
