Label sizes on 4k / retina displays

[Tom Goddard]

Specifying label sizes in pixels makes their initial size very different between 4k / retina and older displays. Maybe sizes should be specified in points, or "high dpi" displays should use a pixel scale of 2.

Hi all,

I spent some time meeting with Jim Proctor and his team in Dundee and one piece of feedback is that the font size for labels was way too small. I investigated this some (since it didn't appear small on my machine) and realized that they were using 4K monitors. I know Tom did some work to make the graphics window work for higher density displays (e.g. Retina), but my guess is that no changes were made to scale the label sizes accordingly.

P.S. Channeling Elaine, yes the user can just change it, but the use case here is that Chimera is being used as a molecular viewer for JalView and the users are probably not familiar enough with Chimera to change it. Furthermore, there is no way that JalView can change it using the REST interface...

P.P.S. This is not necessarily a request for a change to Chimera 1, but we should certainly take into account screen density to scale our font sizes in ChimeraX (e.g. a 12 point font should still be 12 point, regardless of screen density).
