First steps to fix the scaling bug of CID-keyed CFF subfonts, reported by Ding Li on 2008/03/28 on freetype-devel. * src/base/cff/cffparse.c (power_tens): New array. (cff_parse_real): Rewritten to introduce a fourth parameter which returns the `scaling' of the real number so that we have no precision loss. This is not used yet. Update all callers. (cff_parse_fixed_thousand): Replace with... (cff_parse_fixed_scaled): This function. Update all callers.
