Message : * src/truetype/ttgload.c (TT_Load_Glyph): finally fixing the last bug that prevented FreeType 2.x and FreeType 1.x to produce bit-by-bit identical monochrome glyph bitmaps with native TrueType hinting. The culprit was a single-bit flag that wasn't set correctly by the TrueType glyph loader !! * src/otlayout/otlayout.h, src/otlayout/otlbase.c, src/otlayout/otlbase.h, src/otlayout/otlconf.h, src/otlayout/otlgdef.c, src/otlayout/otlgdef.h, src/otlayout/otlgpos.c, src/otlayout/otlgpos.h, src/otlayout/otlgsub.c, src/otlayout/otlgsub.h, src/otlayout/otljstf.c, src/otlayout/otljstf.h, src/otlayout/otltable.c, src/otlayout/otltable.h, src/otlayout/otltags.h: adding OpenType Layout source files. Module is still incomplete
