Werner Lemberg ba67957d5e Fix Savannah bug #35660.
For some divisions, we use casts to 32bit entities.  Always guard
against division by zero with these casts also.

* src/base/ftcalc.c (ft_div64by32): Remove redundant cast.
(FT_MulDiv, FT_MulDiv_No_Round): Add 32bit cast.
(FT_DivFix): Add 32bit cast (this omission triggered the bug).

Werner Lemberg ceed93e328 [psaux] Fix handling of track kerning.
* src/psaux/afmparse.c (afm_parse_track_kern): Don't inverse sign
for `min_kern'.  It is indeed quite common that track kerning
*increases* spacing for very small sizes.

Werner Lemberg 292144b44a [psaux] Fix Savannah bug #35657.
If in function `skip_spaces' the routine `skip_comment' comes to the
end of buffer, `cur' is still increased by one, so we need to check
for `p >= limit' and not `p == limit'.

* src/psaux/psconv.c (PS_Conv_Strtol, PS_Conv_ToFixed,
PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Fix boundary checking.

modify twilight points.

Werner Lemberg cee5d59358 [bdf] Fix Savannah bug #35643.

five `field' elements.

* src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if

variable might be undefined otherwise.
