     // - During Resize callback, Buf will be same as your input buffer.
     // - However, during Completion/History/Always callback, Buf always points to our own internal data (it is not the same as your buffer)! Changes to it will be reflected into your own buffer shortly after the callback.
     // - To modify the text buffer in a callback, prefer using the InsertChars() / DeleteChars() function. InsertChars() will take care of calling the resize callback if necessary.
     // - If you know your edits are not going to resize the underlying buffer allocation, you may modify the contents of 'Buf[]' directly. You need to update 'BufTextLen' accordingly (0 <= BufTextLen < BufSize) and set 'BufDirty'' to true so InputText can update its internal state.
