Somebody on twitter told me that Ubuntu uses a special patch for
freetype that improves font rendering manifolds.
So I rebuilt freetype with these useflags: +auto-hinter +bindist
When you emerge freetype, it tells you at the end that the bindist USE
flag does not longer control the auto-hinter.
Also, as another poster mentioned, this is no longer an issue. The
patent expired so the auto-hinter is no longer required.
What is the difference between this unpatented auto hinter and the
TrueType BC interpreter?
The main difference is that the auto-hinter doesn't take into account
the font's hinting instructions, resulting in non-optimal hinting. In
short: don't use it.
For best looking fonts, disable both the "auto-hinter" and "bindist" USE
flags. The bindist USE flag controls the subpixel-rendering algorithm,
which is still patented by Microsoft in the USA.
So for best results (which is what Ubuntu uses), you need the BC
interpreter (you get that by disabling the "auto-hinter" flag) and the
subpixel renderer (by disabling the "bindist" flag).
