[ft] Subpixel Hinting Patch

[Moony]

This one adds back a couple features that the older patches had, that do 
apparently follow the whitepaper after all.  DejaVu fonts are fixed as 
well as Palatino Linotype, italics, and some glyph shapes (e.g. w x y 
z).  Some regressions in Courier New.  Not intended to be a totally 
clean patch, but should perform well overall.
