  * src/base/ftpfr.c, src/pfr/pfrtypes.h, src/pfr/pfrload.c, src/pfr/pfrobjs.c: fixing PFR kerning support. The tables within the font file contain (charcode,charcode) kerning pairs, we need to convert them to (gindex,gindex) ! * include/freetype/ftoption.h: commenting out the macro TT_CONFIG_OPTION_BYTECODE_INTERPRETER
