* include/freetype/config/ftstdlib.h (FT_LONG_MIN): New macro.

* src/cff/cffparse.c (cff_parse_font_matrix): Use largest scaling
value of all matrix coefficients to scale matrix.

0b3cb8a8af [cff, truetype] Fix logic for `FT_Property_Set'.
Otherwise some properties could be set to arbitrary values, which is
harmless, but querying could give wrong positive results.

* src/cff/cffdrivr.c (cff_property_set) [hinting-engine],
* src/truetype/ttdriver.c (tt_property_set) [interpreter-version]:
Only allow defined values.

f1c93439b9 [cff] Avoid overflow/module arithmetic.
This modifies the addition of subroutine number to subroutine bias
from unsigned to signed, but does not change any results.

* src/cff/cf2ft.c (cf2_initGlobalRegionBuffer,
cf2_initLocalRegionBuffer): Change variable names from (unsigned)
`idx' to (signed) `subrNum', since it is not an index until after
the bias is added.
* src/cff/cf2ft.h: Updated.

14d6b5d748 [truetype] Introduce named instance access to GX fonts.
For functions querying a face, bits 16-30 of the face index can hold
the named instance index if we have a GX font.  The indices start
with value 1; value 0 indicates font access without GX variation
data.

31d97df99f Make Jam support work again.
This is just very basic stuff and just a little bit tested on
GNU/Linux only.  I won't delve into this since I'm not a Jam user.

* Jamfile: Call `HDRMACRO' for `ftserv.h' also.
(DEFINES): Replace with...
(CCFLAGS): ... this.

* src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is
already handled in the top-level Jamfile.

* src/autofit/Jamfile (DEFINES): Replace with...
(CCFLAGS): ... this.
(_sources): Add missing files.

* src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no
longer contains macro header definitions.

* src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile,

a87fb8ccf3 [cff] Make the `*curveto' operators more tolerant.
* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
pulling values off the stack until the stack is exhausted.
Implicitly the stack must be a multiple (or for subtly different
behaviour) a multiple plus a specific number of extra values deep.
If that's not the case, enforce it (as the old code did).

incremental interface callback to apply the encoding to raw
character index (as it was in the previous code).
