- [cache] Fix a possible overflow by signed integer comparison.
+ [psaux] Fix Type 1 glyphs with too many stem hints.
- Improve the code by 5d3ff05615dda6d1325ed612381a17a0df04c975 ,
- issues are found by Behdad Esfahbod and Werner Lemberg.
+ According to the CFF specification, charstrings can have up to 96 stem
+ hints. Due to hint replacement routines in Type 1 charstrings, some
+ glyphs are rejected by the Adobe engine, which implements the above
+ limit. This fix turns off hinting for such glyphs.
- * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Replace
- a subtraction to check higher bit by a bit operation,
- and cpp-conditionalize for appropriate systems. Add better
- documentation to the comment.
- (FTC_ImageCache_LookupScaler): Ditto.
- (FTC_SBitCache_Lookup): Ditto.

+ This is necessary in case the application's memory routines differ

- LastResort.dfont has a marginal resource ID 0xFFFF for sfnt

- FreeType2 just uses resource ID to sort the fragmented resource.
- To accept the marginal fonts, the checking is removed.

- * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Remove res_id

+2017-12-31 Werner Lemberg <wl(a)gnu.org>
- The first 32bit of standard TrueType variants is 0x00010000,
- `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac
- OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
- starting 0xA5 followed by `kbd' or `lst'. Considering the following
- data could be parsed as conventional TrueType fonts, the header
- checking is updated to allow these tags. It seems that recent Mac
- OS X has already switched to normal TTF for these fonts.

+2017-12-31 Werner Lemberg <wl(a)gnu.org>
- Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
- buffer if it became too small; it didn't make the buffer smaller.
- For an empty bitmap following a non-empty one, only the buffer
- dimension got set to zero, without deallocation. If the next call

- At least on FreeBSD there is a global declaration of `index' in file

+ Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
+ buffer if it became too small; it didn't make the buffer smaller.
+ For an empty bitmap following a non-empty one, only the buffer
+ dimension got set to zero, without deallocation. If the next call

- [autofit] Prevent overlapping blue zones.
-
- Problem reported as
-
- https://github.com/google/fonts/issues/632
-
- The font in question (Nunito) has values 705 and 713 for the
- reference and overshoot values, respectively, of the first blue
- zone. Blue zone 2, however, has value 710 for both the reference
- and overshoot. At 12ppem, reference and overshoot of blue zone 0
- becomes 8px, while blue zone 2 becomes 9px.
-
- A peculiarity of this font is that the tops of isolated vertical
- stems like `N' have a slight overshoot also. The auto-hinter tries
- to find the nearest blue zone using the *original* coordinates. For
- vertical stems, this is value 713. For normal horizontal tops like
- in character `E', this is value 710. Since value 713 is mapped to
- 8px but value 710 to 9px, `N' and similar characters are one pixel
- higher than `E', which looks very bad.
-
- This commit sanitizes blue zones to avoid such a behaviour.

- [autofit] Use better blue zone characters for lowercase latin.
