not available.

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.

In function parse_font_matrix, added heuristic to get units_per_EM
from the font matrix.
In parse_dict, deleted test to see if the FontInfo keyword has been
seen. Deletion of this test allows fonts without FontInfo
dictionaries to be parsed by the Type 1 driver.
In T1_Open_Face, deleted empty subroutines array test to make sure
fonts with no subroutines still are parsed.
