  * include/freetype/internal/internal.h, include/freetype/ftpfr.h, src/base/ftpfr.c, src/base/Jamfile, src/descrip.mms, src/rules.mk, src/pfr/pfrdrivr.c, src/pfr/pfrobjs.c, src/pfr/pfsobjs.h: added PFR-specific public API. Fixed the kerning retrievel routine (it returned invalid values when the outline and metrics resolution differ) * src/base/ftsynth.c: fixed the synthetic emboldener. at last. * src/base/ftobjs.c: small internal fix to better support bitmap-based font formats
