Struct SpanImageResampleAffine 

pub struct SpanImageResampleAffine<'a> { /* private fields */ }

Image resampling state for affine transformations.

Computes scale factors from the interpolator’s affine matrix once per scanline (in prepare()), limiting them to avoid excessive filter expansion.

Port of C++ span_image_resample_affine<Source>.
