I have done tests on this some time ago, in which I wanted to use the font 
size as an additional parameter to calculate the minimum width of the grid.
I think 'ex'es an 'em's are better choices to use in user interfaces.
Still, I think no configuration would be the better solution.
But nobody seem to agree on what is reasonable in this field, so...

In my experiment, I restrict gridX to be at least fontMetrics().height() * 7
which gives roughly the current spacing with normal/small fonts, and larger 
spacing for proportionately larger fonts.
I have not submitted the change because I have not found (yet) how to 
refresh the view on font-size changes. Without that, ugly artifacts appeear 
when adjusting font size from the control center.

Here is the relevant lines of my change, maybe they could be useful, after
