- Fixed a rather annoying bug that was introduced in 2.0.3. Namely, the

I. CHANGES TO THE MODULES / FONT DRIVERS
- THE AUTO-HINTER HAS BEEN SLIGHTLY IMPROVED, in order to fix several
annoying artefacts, mainly:
- blue zone alignement of horizontal stems wasn't performed
correctly, resulting in artefacts like the "d" being placed
one pixel below the "b" in some fonts like Time New Roman
- Blue zone alignement of horizontal stems wasn't performed
correctly, resulting in artefacts like the "d" being placed one

- overshoot thresholding wasn't performed correctly, creating
unpleasant artefacts at large character pixel sizes

- Composite glyph loading has been simplified. This gets rid
of various artefacts where the components of a composite glyphs
were not correctly spaced.
These are the last changes to the current auto-hinting module.
A new hinting sub-system is currently in the work in order to
support native hints in Type 1 / CFF / OpenType fonts, as well
as globally improve rendering
