Shouldn't this be some multiple of the display scale by default?  If
not, tabs will end up tiny for users of high-resolution displays.

I tried Double (HiDPI) in Firefox, and it changes the Firefox tab width
from 220 to 440 pixels.  But at the same time it also changes
the sizes of all used fonts, that Emacs doesn't do.  So the first task
would be to implement the display scaling applied to Emacs faces.
