7ec694ddf2 Use non-GRID-fitted values for metrics (#1363) 
* Use non-GRID-fitted values for metrics

See freetype/src/base/ftobjs.c:ft_recompute_scaled_metrics() and
the usage of GRID_FIT_METRICS inside.

Fixes https://github.com/behdad/harfbuzz/issues/1262

* Update hb-ft.cc

9c04b60583 [kern] In Format1, adjust how kerning is done 
In a series of kerns in one action, kern all but last glyph forward,
and the last one backward.  Seems to better match what CoreText is doing.

Test cases, with GeezaPro Arabic:

$ ./hb-shape GeezaPro_10_10.ttc -u U+0631,U+0628
[u0628.beh=1+1415|u0631.reh=0@-202,0+700]

$ ./hb-shape GeezaPro_10_10.ttc -u U+0628,U+064F
[u064f.damma=0@0,-250+-250|u0628.beh=0@250,0+1665]

In a later change, I'll make kern machine avoid producing negative kerns.

e8c4772463 [kern] XXX Negate CrossKerning sign 
Not sure why, but seems to better match GeezaPro Arabic w CoreText.

Quite possibly I'm doing something very wrong...
