Please don't rely on the type of jxl_fmt.align here (which is out of our control). E.g. in the future it may be that libjxl supports only 32bit align values (i.e. uses uint32_t or so for it), but that we support 64bit (ptrdiff_t) linesizes and allocations, so that jxl_fmt.align * (info.ysize - 1) may overflow this even when -linesize fits into jxl_fmt.align. (Very unlikely given that align is size_t and they will likely not go back from this, but it could happen.)
This would be an ABI break though, wouldn't it? Why do we need to work around a potential future ABI break?
