b972a2a294 Generalize the concept of `tricky' fonts by introducing 
FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
engine is necessary for correct rendering.

At the same time, slightly modify the behaviour of tricky fonts:
FT_LOAD_NO_HINTING is now ignored.  To really force raw loading
of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
FT_LOAD_NO_AUTOHINT must be used.

Finally, tricky TrueType fonts always use the bytecode interpreter
even if the patented code is used.

* include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
New macros.

* src/truetype/ttdriver.c (Load_Glyph): Handle new load flags
semantics as described above.

* src/truetype/ttobjs.c (tt_check_trickyness): New function, using
code of ...
(tt_face_init): This function, now simplified and updated to new
semantics.

* src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky
fonts.

* docs/CHANGES: Document it.

1474f439b5 Really fix Savannah bug #25010: An SFNT font with neither outlines 
nor bitmaps can be considered as containing space `glyphs' only.

* src/truetype/ttpload.c (tt_face_load_loca): Handle the case where
a `glyf' table is missing.

* src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no
`glyf' table but a non-zero `loca' entry.
(tt_loader_init): Handle missing `glyf' table.

* src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05.

* src/sfnt/sfobjs.c (sfnt_load_face): A font with neither outlines
nor bitmaps is scalable.

76fffcd898 * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value 
0x100 instead of 0x10000; the latter value is already occupied by
FT_LOAD_TARGET_LIGHT.  Bug reported by James Cloos.


Handle SFNT with neither outlines nor bitmaps.  This fixes Savannah
bug #25010.

* src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither
outlines nor bitmaps.

* src/sfnt/sfobjs.c (sfnt_load_face): Don't return an error if there
is no table with glyphs.


* src/sfnt/ttload.c (tt_face_lookup_table): Improve debugging
message.


Other minor cosmetics.

b2cb6ce6c4 * src/type1/t1load.c (mm_axis_unmap): `blend_points' is FT_Fixed*, 
whereas `design_points' is FT_Long*.  Therefore, return blend rather
than design points.
