38		* Testing a HiDPI display is difficult without running in a HiDPI display.
39		* The gathering of screen size and resolution performed by jalview.bin.HiDPISetting
40		* is now farmed out into a separate class jalview.bin.ScreenInfo so it can be more
41		* easily Mocked in tests.
42		* Two sets of tests are performed.
43		* 1) testLinuxScalePropertyToActualTransform() sets the property that HiDPISetting
44		* uses (via jalview.bin.Launcher or getdown) to scale up Jalview, and then looks at
45		* the alignment panel graphics2d transform to see if it's been scaled by the same
46		* amount (in this case 4 -- unlikely to happen by accident!).
47		* 2) testHiDPISettingInit() which tests the calculation that HiDPISetting uses to
48		* decide from apparent screen information (mocked using Mockito in the tests) what
49		* scaling factor to set (it doesn't actually set it, just suggests it to
50		* jalview.bin.Launcher)
