Henri Verbeet 34a9400a89 usp10: Validate positioning record sequence indices in GPOS_apply_ChainContextPos(). 
The issue is somewhat theoretical, since in reasonbale fonts the indices
should always be valid, and in fact are fairly likely to be 0. On the other
hand, web fonts exist.

Henri Verbeet 0389768568 usp10: Return early if the number of positioning operations is 0 in GPOS_apply_ChainContextPos(). 
This preserves the current logic, but I wonder if we're not supposed to always
return "input_count". Returning 1 seems questionable if we matched more input
glyphs than that, and so does including the lookahead count.

Henri Verbeet 7dfe9b9c94 usp10: Range check glyph counts in GPOS_apply_ChainContextPos(). 
I.e., avoid accessing outside the "glyphs" array. If we're particularly
unlucky we may actually get a match against data outside the array.
