Ken Sharp 8ea31415f4 Fix Savannah bug #28521.
Issue #28226 involved a work-around for a font which used the
`setcurrentpoint' operator in an invalid way; this operator is only
supposed to be used with the result of OtherSubrs, and the font used
it directly.  The supplied patch removed the block of code which
checked this usage entirely.

This turns out to be a Bad Thing.  If `setcurrentpoint' is being
used correctly it should reset the flex flag in the decoder.  If we
don't do this then the flag never gets reset and we omit any further
contours from the glyph (at least until we close the path or
similar).

* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
<op_setcurrentpoint>: Handle `flex_state' correctly.

Ralph Giles bc0082d512 Improve the comment describing the FT_CONFIG_OPTION_INCREMENTAL option. 2010-01-05 19:41:22 +01:00
Ralph Giles e383729536 Enable the incremental font interface by default.
Ghostscript requires the incremental font interface for handling
some Postscript documents.  It is moving to using FreeType as its
primary renderer; supporting this in the default build makes it
Ghostscript to be linked against the system FreeType when one is
available.

* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
Uncomment.

Ken Sharp ce41259372 Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
This fixes Savannah bug #28226.

At least two wild PostScript files of unknown provenance contain
Type 1 fonts, apparently converted from TrueType fonts in earlier
PDF versions of the files, which use the `setcurrentpoint' operator
inappropriately.

FreeType currently throws an error in this case, but Ghostscript and
Adobe Distiller both accept the fonts and ignore the problem.  This
commit #ifdefs out the check so PostScript interpreters using
FreeType can render these files.

The specification says `setcurrentpoint' should only be used to set
the point after a `Subr' call, but these fonts use it to set the
initial point to (0,0).  Unnecessarily so, as they correctly use an
`hsbw' operation which implicitly sets the initial point.
