Fri 29 Mar 2013 06:43:48 PM UTC, comment #2: FreeType already has code which does what you are suggesting, I think. You can activate it by defining AF_CONFIG_OPTION_USE_WARPER; the source code is in file src/autofit/afwarp.c. Improvements to this code are highly welcomed :-)

Fri 29 Mar 2013 10:09:53 AM UTC, original submission:
One of the objectives of hinting is to improve the contrast of the glyph bitmap by moving the control points either by program or by an automatic heuristic such that the control points would match with the pixel grid. Hinting has the problem that the program must match the expectation of the glyph rasterizer, or for instance diagonal stem in Times New Roman z tends to vanish. The autohinter, on the other hand, doesn't always preserve glyph symmetry, which leads to results that are perceived as artifacting.
