Fetches a list of the caret positions defined for a ligature glyph in the GDEF
table of the font. The list returned will begin at the offset provided.
Note that a ligature that is formed from n characters will have n-1
caret positions. The first character is not represented in the array,
since its caret position is the glyph position.
The positions returned by this function are 'unshaped', and will have to
be fixed up for kerning that may be applied to the ligature glyph.
