Jonathan Kew 0d1262a41e [sfnt] Fix `premultiply_data' (#52092).
* src/sfnt/pngshim.c (premultiply_data): Don't use vector extension
if we have less than 16 bytes of data.

Werner Lemberg 6d403d089d Fix handling of ValueRecords.
For GPOS pair positioning format 1 the description of ValueRecords
in the OpenType specification (1.8.2, from today) is wrong – the
offset has to be taken from the parent structure; in this case the
`PairSet' table.

* src/otvalid/otvgpos.c (otv_PairSet_validate): Set `extra3'.
(otv_PairPos_validate): Adjust.

John Tytgat b00be9f609 [cff] Fix family name logic of pure CFF fontdata (#52056).
1. If `FamilyName' is present in the CFF font, use this for
   FT_Face's `family_name'.
2. Otherwise, use the face name and chop off any subset prefix.
3. If at this point FT_Face's `family_name' is set, use this
   together with the full name to determine the style.
4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
5. If we don't have a valid style, use "Regular".

Previously, FT_Face's `family_name' entry for pure CFF fontdata
nearly always was the fontname itself, instead of the `FamilyName'
entry in the CFF font (assuming there is one).

* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.

suzuki toshiya 3ef59e59e0 [base] Remove a check for resource ID in the resource fork driver.
LastResort.dfont has a marginal resource ID 0xFFFF for sfnt
resource.  Inside Macintosh: More Macintosh Toolbox, `Resource IDs'
(1-46), tells that some IDs are reserved and should not be used.
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
validity check, fix a trace message format.

suzuki toshiya 5c4e40d7fd [sfnt, truetype] Register the tags for marginal fonts.
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.

See the discussion at
http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0

* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header
tags for Keyboard.dfont and LastResort.dfont.
* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource
starts with TTAG_0xA5kbd or TTAG_0xA5lst.
* src/truetype/ttobjs.c (tt_face_init): Accept the face with the
format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

Werner Lemberg a3dd6d99a4 Fix multiple calls of `FT_Bitmap_Convert'.
The documentation of `FT_Bitmap_Convert' says that multiple calls do
proper reallocation of the target FT_Bitmap object.  However, this
failed for the sequence

  non-empty bitmap
  empty bitmap
  non-empty bitmap

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
was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
triggered.

* src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target
buffer to the correct size.

* docs/CHANGES: Document it.
