Re: [ft] Modifying/Enhancing the Truetype Interpreter

Werner,

I am totally fine with calling this whatever you'd like.  "Subpixel 
hinting" makes sense to me.

2010-03-10:
* Changed the function names to end in _sph instead of _ttslight
* Added code back in that deals with x, and divided "distance" by 32, 
instead of ignoring completely.
* Removed modifications from the unpatented hinting section
* Made ALIGNPTS use _sph, which supposedly doesn't matter, but helps 
some legacy italics.
* A couple other things maybe.  Overall not too different from last 
patch version.

Screenshot of the patch in action, with various fonts, in WINE Wordpad.  
There are artifacts with some fonts / glyphs that will probably have to 
have TT function calls disabled in order to render better:
