* builds/unix/ftconfig.in, builds/vms/ftconfig.h: Define 

FT_CHAR_BIT.

* src/base/ftobjs.c (FT_Load_Glyph): Don't apply autohinting if
glyph is vertically distorted or mirrored.

* src/cff/cffgload.c (cff_slot_load): Handle zero `size' properly
for embedded bitmaps.

* docs/CHANGES: Updated.

- The native TrueType hinter contained some bugs which prevented
some fonts to be rendered correctly, most notably Legendum.otf.

- The linear advance width and height values were incorrectly

- Metrics for BDF and PCF bitmap font formats have been fixed.
- Autohinting is now disabled for glyphs which are vertically
distorted or mirrored (using a transformation matrix). This
fixes a bug which produced zero-height glyphs.
- The `freetype-config' script now handles --prefix and
--exec-prefix correctly; it also returns the proper --rpath (or
-R) value if FreeType has been built as a shared library.
