// autocxx (built on cxx) cannot bind functions that take a `void**` argument,
// i.e. a pointer to an opaque `void*` handle. In InspireFace, HFImageBitmap,
// HFImageStream and HFSession are all `typedef void*`, so their out-parameters
// (PHFImageBitmap / PHFImageStream / PHFSession, all `void**`) make autocxx
// silently drop the wrapper for those functions.
//
// These thin inline wrappers return the handle through the return value
// instead, so the signature only ever uses a single-level `void*` plus an
// `HResult*` out-param, both of which autocxx binds cleanly.
