A max-pool, a channel-copy 2x2 transposed convolution (mode 1) and the
channel-copy 1x1 layer give an exact answer, so a store fault in mode 1
can't hide in tolerance (CodeRabbit review of #2380).
On the GTX 1070 this test passes even without mode 1's stepped stores:
FXC merges them the same way, but the driver runs that store right, so
only mode 0 was shown wrong. Mode 1 keeps the stepped stores as a
precaution; the shader comment and docs/gpu-pipeline.md now say so.
