Nathan Reed: warning fixes for 1.0
REVISIONS
2.15 (2025-07-17) fixed an assert in debug mode when using floats with input
callbacks, work around GCC warning when adding to null ptr
(thanks Johannes Spohr and Pyry Kovanen).
2.14 (2025-05-09) fixed a bug using downsampling gather horizontal first, and
scatter with vertical first.
2.13 (2025-02-27) fixed a bug when using input callbacks, turned off simd for
