Also, check out the dpi settings for your display (xdpyinfo). If this
is set lower than the physical reality, then pointsizes are
overestimated (so fonts are smaller than they should be). How to
change it is left as an exercise....

BTW, it's 1.9.1, 1.91 is not in the plans (and wouldn't be for the
next forty years or so).
