Detailed Description

2D spatial filtering on normalised float image spans.

Pure functions. No MayaFlux type dependencies.

Conventions

All inputs are single-channel normalised float in [0, 1] unless noted
w and h are pixel dimensions; caller ensures span size == w * h
Border handling is clamp-to-edge throughout
Separable filters decompose into two 1D passes for O(w*h*k) cost rather than O(w*h*k^2)
Parallelism handled internally via Parallel::par_unseq
