LATEST_CHANGES
+ - fixed potential "divide by zero" bugs in ftcalc.c.. my god..
+
+ - added source code for the OpenType/CFF driver (still incomplete though..)
+
+ - modified the SFNT driver slightly to perform more robust header
+ checks in TT_Load_SFNT_Header. This prevents certain font files
+ (e.g. some Type 1 Multiple Masters) from being incorrectly "recognized"
+ as TrueType font files..
+
- moved a lot of stuff from the TrueType driver to the SFNT module,
this allows greater code re-use between font drivers (e.g. TrueType,
OpenType, Compact-TrueType, etc..)
