YuiImageSamplingCoordinateQ16V1

Maps one destination coordinate onto the inclusive source span without the potentially overflowing output*source*65536 product. Quotient/remainder decomposition is exactly floor((output * sourceSpan * 65536) / outputSpan).

Notes and source

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
