[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.
