|
Fix Savannah bug #29846.
|
|
|
|
Previously we discovered fonts which used `setcurrentpoint' to set
|
|
the initial point of a contour to 0,0. This caused FreeType to
|
|
raise an error, because the `setcurrentpoint' operator is only
|
|
supposed to be used with the results from an OtherSubr subroutine.
|
|
|
|
This was fixed by simply ignoring the error and carrying on.
|
|
|
|
Now we have found a font which uses setcurrentpoint to actually
|
|
establish a non-zero point for a contour during the course of a
|
|
glyph program. FWIW, these files may be produced by an application
|
|
called `Intaglio' on the Mac, when converting TrueType fonts to
|
|
Type 1.
|
|
|
|
The fix allows the new invalid behaviour, the old invalid behaviour
|
|
and real proper usage of the operator to work the same way as Adobe
|
|
interpreters apparently do.
|
|
|
|
(t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top
|
|
two elements of the stack to establish unconditionally the current x
|
|
and y coordinates.
|
|
|
|
Make the `flex' subroutine handling (OtherSubr 0) put the current
|
|
x,y coordinates onto the stack, instead of two dummy uninitialised
|
|
values.
