* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM,
cf2_cmdVSTEM, cf2_cmdHINTMASK>: Don't append to stem arrays after
hintmask is constructed.
* src/cff/cf2hints.c (cf2_hintmap_build): Add defensive code to
avoid reading past end of hintmask.
This is for `FT_Get_Advance'.
There are 7 places where the spec says the width can be defined:
hstem/hstemhm
vstem/vstemhm
cntrmask/hintmask
hmoveto
vmoveto
rmoveto
endchar
* src/cff/cf2intrp.c (cf2_doStems): Exit early for width-only calls,
if possible.
(cf2_interpT2CharString) <cf2_cmdHSTEM>, <cf2_cmdVSTEM>,
<cf2_cmdVMOVETO>, <cf2_cmdENDCHAR>, <cf2_cmdHINTMASK>,
<cf2_cmdRMOVETO>, <cf2_cmdHMOVETO>: Exit early for width-only calls.
* include/freetype/internal/ftstream.h: Simplify and fix integer
extraction macros.
(FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32,
FT_INT8_I32, FT_INT8_U32): Removed.
(FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE,
FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for
computations and convert to signed as the last step.
* src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt,
cf2_fracToFixed): Avoid shifts of negative values.
(cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed,
unused.
* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,
default>: Use unsigned values for computations and convert to signed
as the last step.
Use proper types in tracing messages.
* src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned
values for computation of operands and convert to signed as the last
step.
Use proper type in tracing message.
