[truetype] Fix positioning of composite glyphs.
Problem reported by Nigel Tao <nigeltao@golang.org>.
* src/truetype/ttgload.c (TT_Hint_Glyph): Remove code that shifts
the glyph (component) by a fractional value computed from the LSB
phantom point. This is wrong, since the horizontal phantom points
get rounded horizontally later on.
