David Turner 01ca4da203 Remove ABI-breaking field in public PS_InfoFontRec definition.
Instead, we define a new internal PS_FontExtraRec structure to
    hold the additionnal field, then place it in various internal
    positions of the corresponding FT_Face derived objects.

Werner Lemberg e5a7cc239c Fix handling of EBDT formats 8 and 9.
The main cycle in `blit_sbit' makes too many iterations: it actually
needs the count of lines in the source bitmap rather than in the
target image.

* src/sfnt/ttsbit.c (blit_sbit) [FT_CONFIG_OPTION_OLD_INTERNALS]:
Add parameter `source_height' and use it for main loop.
(Load_SBit_Single) [FT_CONFIG_OPTION_OLD_INTERNALS]: Updated.

Werner Lemberg c2cabd4291 Fix Savannah bug #25495.
* src/sfnt/sfobjs.c (sfnt_load_face): Test for bitmap strikes before
setting metrics and bbox values.  This ensures that the check for a
font with neither a `glyf' table nor bitmap strikes can be performed
early enough to set metrics and bbox values too.

Werner Lemberg ce33a312da FT_USE_MODULE declares things as:
extern const FT_Module_Class

(or similar for C++).  However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class.  (Some are, indeed, FT_Module_Class.)

This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.

To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:

  All declarations that refer to the same object or function shall
  have compatible type; otherwise, the behavior is undefined.

(And they are not compatible types.)

Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does.  (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)

Patch from Savannah bug #25133.

* src/base/ftinit.c (FT_USE_MODULE): Include variable type.

* builds/amiga/include/freetype/config/ftmodule.h,

Werner Lemberg 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.

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.
