SpreadProcessing: The VisibleRange of ViewportPane is wrong when column widths use sizes with big decimal precision
When the columns are using widths with too precise decimal values (ex: 150.33333333333334), the VisibleRange of ViewportPane reports wrong range in some situations.
This causes issues when calculating element positions in a custom WorksheetUILayerBase in the context of RadSpreadsheet for WPF.
