RFR: 8299753: Tree/TableView: Column Resizing With Fractional Scale [v4]

[Andy Goryachev]

> Modified the resize algorithm to work well with fractional scale, thanks for deeper understanding of the problem thanks to  @hjohn and @mstr2 .
> 
> It is important to note that even though the constraints are given by the user in unsnapped coordinates, they are converted to snapped values, since the snapped values correspond to the actual pixels on the display.  This means the tests that validate honoring constraints should, in all the cases where (scale != 1.0), assume possibly error not exceeding (1.0 / scale) (I think).
