[tx] coding bug in cffread saveDeltaArray()

[blueshade7]

cffread.c line 893 reads:

blendEntry->value = lastValue + (stackEntry->is_int) ? (float)stackEntry->u.int_val : stackEntry->u.real_val;

It should read:

blendEntry->value = lastValue + (stackEntry->is_int ? (float)stackEntry->u.int_val : stackEntry->u.real_val);

Otherwise wrong or garbage values may be parsed out as values of BlueValues etc in a Private dict in a CFF2 variable font.
