clip_*_uint32_t() returns 0 when v == 1.f because it computes the result
as (IN_T)((v * ((mixeng_real)IN_MAX / 2.f)) + HALF):
- (v * ((mixeng_real)IN_MAX / 2.f)) + HALF == 0x100000000.f, which does
not fit in uint32_t.
- (v * ((mixeng_real)IN_MAX / 2.f)) == 0x80000000.f
- ((mixeng_real)IN_MAX / 2.f) == 0x80000000.f
- (mixeng_real)IN_MAX == 0x100000000.f because 0xffffffff cannot be
represented exactly in float.
- HALF == 0x7fffffff, which is implicitly converted to 0x80000000.f.
Clamp the result to avoid the overflow.
