* src/type1/t1objs.c (T1_Init_Face): Added code to get the
units_per_EM from the value assigned in parse_font_matrix, if
available. Default to 1000 if not available.
* src/cff/cffparse.c (cff_parse_font_matrix): Added logic to get
the units_per_EM from the FontMatrix.
(cff_parse_fixed_thousand): New function. 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).
(cff_parse_real): Added code so that the integer part is moved
into the high sixteen bits of the 16.16 fixed number.
* src/cff/cffobjs.c (CFF_Init_Face): Added logic to get the units
per EM from the CFF dictionary, if available.
* include/freetype/internal/cfftypes.h: In struct CFF_Font_Dict_,
added a units_per_em member to facilitate passing of units_per_em
from function cff_parse_font_matrix.
