Comments
A recognizer
is not required to use or maintain OEM data; that is, a recognizer may choose
to ignore some or all of the OEM data it receives from AddPenInputHRC.
This means that the HPENDATA object that the recognizer returns through
its CreatePenDataHRC
function may differ from hpndt in its OEM data.
