Added patch #412132 (Fix for bug #215410) (Mainly in CalcDimensions()),
        changing GRID_SCROLL_LINE to 1.
Fixed Bug #413014 (Missing refresh after calling DeleteCols) by fixing
        Redimension.
Fixed Bug #232657 (Mouse not captured during wxGrid column resize) by
        fixing ChangeCursorMode.
Fixed some minor problems with screen updates (CalcDimensions should only be
        called while not BatchMode, Autosizing Rows/Cols should happen within
        BatchMode, Sizing a row/column should update also labels)
        - touched various functions.
