% XXXgijs This is the ugliest bit of code I think I've ever written for Mozilla.
% Basically, the 0.1px is there to avoid CSS rounding errors causing buttons to wrap.
% For gory details, refer to https://bugzilla.mozilla.org/show_bug.cgi?id=963365#c11
% There's no calc() here (and therefore lots of calc() where this is used) because
% we don't support nested calc(): https://bugzilla.mozilla.org/show_bug.cgi?id=968761
