RFR: 8233068: HIDPI: Linux: AWT Checkbox check mark is unscaled [v2]

[Tejesh R]

> The check mark had been transformed with default scale which is 1.0 and the same is used on click of checkbox. This was done while computing the layout and not updated while paint. Hence the scaling update is done on painting the check mark and CI testing is green after the update too.

Tejesh R has updated the pull request incrementally with two additional commits since the last revision:

 - Color updation
 - Test condition updated + Copyright year
