True, but for the clock font it would actually be desirable that it 
adapts. The main problem, however, is that changing the clock font even 
without resize breaks the window sizing, so that part of the board will 
be blank or clipped. This is caused by the method I use for determining 
square size from window size: I start up XBoard with a 1x1 board, and 
after pop up of the window read the size of the outer window. That tells 
me how much height the menu bar + clocks + message/buttons need. And 
then I assume this will be constant during the session, adding it to the 
board height to know how much total window size I must request to 
tightly fit around the board. If the clock font changes, this vertical 
margin should change, but I don't know by how much.

I guess I could read out the height of the clock widget before and after 
the font change, to see how much the 'vertical margin' has to change. 
(And similarly for the message window.)

Once this works adapting the font during resize would not be so 
difficult. First calculate the new square size assuming no font change. 
Then look up what fonts belong to it, and change the clock and message 
font to those. If the clock height decreased by that, you are done. If 
it increased recalculate how much the square size should be with the 
increased clock height, look up what font belongs to that (which would 
normally be smaller, belonging to smaller square size), and use those.
