The ops.h infrastructure currently hard-codes this as SWS_PIXEL_F32, but I want to at least properly parametrize this in case we ever decide to revisit this decision in the future. In particular, it may become relevant for trivial kernels or kernels whose intermediates are bounded, exact integers (which could possibly be output directly as e.g. U16 or U32). The FATE change is just because the filter op names gained a suffix. Sponsored-by: Sovereign Tech Fund Signed-off-by: Niklas Haas <git@haasn.dev>
