[truetype] Recalculate the sfnt table checksum always.
* src/truetype/ttobjs.c (tt_get_sfnt_checksum): Recalculate
the sfnt table checksum even if non-zero value is writte in
the TrueType font header. Some bad PDF generators write
wrong values. For detail, see examples and benchmark tests
of the latency by recalculation:

[truetype] Always check the checksum to identify tricky fonts. Some PDF generators mangle the family name badly, prioritize the check by the sfnt table checksums than the check by the family name.

[truetype] Always check the checksum to identify tricky fonts.
[truetype] Revert the reordering of trickyness checking. Trickyness check by the family name is faster than that by the checksum.
2011-04-25 22:46:12 +04:00
Because some PDF generators mangle the family name badly,
the trickyness check by the checksum should be invoked always.

When a node comparator changes the cached nodes during the search of a node matching with queried properties, the pointers obtained before the functon should be updated to prevent the dereference to freed or reallocated nodes.

* src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
list_changed' to indicate the change of the cache nodes, anyway. It
is updated by `FTC_CACHE_TRYLOOP'.
(FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
passed to `ftc_snode_compare'.
[cache] Notice if a cache query induced the node list change. Some node comparators (comparing the cache node content and the properties specified by the query) can flush the cache node to prevent the cache inflation. The change may invalidate the pointers to the node obtained before the node comparison, so the change should be noticed to the caller. The problem caused by the cache node changing is reported by Harsha, see Savannah bug #31923. * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument `FT_Bool* list_changed' to indicate the change of the cached nodes to the caller.

Apply Savannah patch #7422. If we encouter a space in a string then the sbit buffer is NULL, height and width are 0s. So the check in ftc_snode_compare will always pass for spaces (comparision with 255). Here the comments above the condition are proper but the implementation is not. When we create an snode I think it is the proper way to initialize the width to 255 and then put a check for being equal to 255 in snode compare function. * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with value 255.

If we encounter a space in a string then the sbit buffer is NULL,
Apply Savannah patch #7422. If we encouter a space in a string then the sbit buffer is NULL, height and width are 0s. So the check in ftc_snode_compare will always pass for spaces (comparision with 255). Here the comments above the condition are proper but the implementation is not. When we create an snode I think it is the proper way to initialize the width to 255 and then put a check for being equal to 255 in snode compare function. * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with value 255. (ftc_snode_compare): Fix condition.

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.
