Detailed Description

Resamples a 2D input field of size (Nx x Ny) to this element's output size (Mx x My).

On each step(), Resize2D reads its input field's "output" component (a y-major flattened Nx x Ny matrix) and resamples it to its own output size (Mx x My) using the configured InterpolationMethod. Resampling is performed separably: each row is resampled along x, then each column along y, reusing the 1D resampling helpers in tools::math. As with Resize, the input and output sizes differ, so addInput() is overridden to size the "input" component to the source's size.
