TAdvStringGrid GetCheckboxState

In TAdvStringGrid, version, the state of a checkbox in cell (liCol, liRow) of a grid with active filter was retrieved into a variable lbState by calling
grid.GetCheckboxState(liCol, liRow, lbState).
To achieve the same in TAdvStringGrid, version,
grid.GetCheckboxState(liCol, grid.RealRowIndex(liRow), lbState)
must be called.
Is this change intended or is it a bug?

This is a change by design. Please use the real row index.
