Note that the negative glyph spacing is const here, regardless of the font scaling. The alternative of using proportional spacing in reality does not work as good as it sounds. With fractional scaling some of the glyphs will no longer land on exact pixel boundaries, which results in blurry text. Looking at the potential solutions for this problem is moot point, as with the non-fractional scale of 2x and glyph spacing of -2, there is no longer enough space separating some letters, which is especially visible in words like "common" or register "xmm", where the "mm" pair becomes joined.
