% Here we implement the scale=MatchLowercase option.
% If this is given, we must compute the correct value of
% the "\Gudea@scale" parameter before loading the .fd files;
% but to determine that value we of course need the font's x-height.
% To avoid triggering the loading of .fd files,
% we use plain TeX's \font primitive to load the testfont.
% We then compute the ratio of the current x-height to our font's x-height;
% this is the "\Gudea@scale" we will pass to the .fd files.
