In function cff_parse_font_matrix, added logic to get the units_per_EM from the FontMatrix. Added a new function (cff_parse_fixed_thousand) that gets a real number fromt he CFF font, but multiplies by 1000 (this is to avoid rounding errors when placing this real number into a 16.16 fixed number). In function cff_parse_real, added code so that the integer part is moved into the high sixtenn bits of the 16.16 fixed number.
