* src/autofit/afhints.h, src/autofit/afhints.c, src/autofit/aftypes.h,
src/autofit/afwarp.c: light auto-hinting, improve glyph advance widths
and ressurect normal/full hinting to its normal quality
For light auto-hinting, improve glyph advance widths and resurrect
normal/full hinting to its normal quality.
* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
and `xmax_delta'.
* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
and `xmax_delta'.
* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
preprocessor conditional with if-clause, handling both light and
normal mode.
* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
(af_warper_compute): Handle `xmin_delta' and `xmax_delta'.
