C++SDK About IWaxStrand::GetTextIndexToWaxLineData
IWaxStrand::GetTextIndexToWaxLineData is being used to obtain coordinates.
It seems to work fine, but when tables with two or more rows exist, it doesn't seem to work properly. Is this a bug?

Modern AI is quite smart. When I asked it how to get character coordinates, it suggested the IWaxStrand::GetTextIndexToWaxLineData method. If it gives an incorrect answer, uploading the interface header seems to make it return much more accurate results.
