/**
* These are the meta data keys used for `IStreamAttributes`. We need to keep
* track of this because `IAttributeList` has no way to just iterate over the
* stored keys. We'll read these from the host if the host supports this
* interface, and if the plugin writes an attribute with one of these keys we'll
* write the value back to the host.
*
* TODO: There's also `Steinberg::Vst::PresetAttributes::kFilePathStringType`
* This would require translating between Windows and Unix style paths,
* which we can't easily do outside of Wine. If this ends up being
* important, then we'll have to shell out to `winepath` which is not
* ideal. On the Wine side we can just use the `wine_get_dos_file_name`
* and `wine_get_unix_file_name` functions instead. Requesting this should
* also use a 1024 character buffer.
