We could skew fonts now if we wanted to. TTF fonts are mostly quadratic Bezier curves so we can redefine what the axes to use when rendering the font glpyhs. Instead of i = (1, 0), j = (0, -1) we can use i = (1, 0) j = (0.3, -1). There's a lot more to fonts obviously like bitmap glyphs, hinting, kerning, etc but we could build in some params if we wanted to.
