* builds/unix/ftsystem.c (FT_New_Stream): added a fix to ensure that
|
||||
all FreeType input streams are closed in child processes of a "fork"
|
||||
on Unix systems. This is important to avoid (potential) access
|
||||
control issues..

|

* src/type1/t1objs.c (T1_Face_Init): fixed a bug that crashed the
|
||||
library when dealing with certain weird fonts (like "Stalingrad",
|
||||
in "sadn.pfb". This font has no full font name entry.. )

|
||||
"sadn.pfb" (this font has no full font name entry).
|
||||
|
||||
* src/base/ftoutln.c, include/freetype/ftoutln.h: added the
|
||||
FT_Outline_Check API to check the consistency of outline data
|
||||
|
||||
* src/base/ftobjs.c (FT_Load_Glyph): added a call to the new
|
||||
FT_Outline_Check to ensure that loaded glyphs are valid. This
|
||||
allows certain fonts like "tt1095m_.ttf" to be loaded even though
|
||||
it appears they contain really funky glyphs..
|
||||
|
||||
there still is a bug there though.. !!
|
||||
* src/base/ftoutln.c, include/freetype/ftoutln.h (FT_Outline_Check):
|
||||
New function to check the consistency of outline data.
|
||||
|
||||
* src/base/ftobjs.c (FT_Load_Glyph): Use `FT_Outline_Check' to
|
||||
ensure that loaded glyphs are valid. This allows certain fonts like
|
||||
"tt1095m_.ttf" to be loaded even though it appears they contain
|
||||
really funky glyphs.
|
||||
|
||||
There still is a bug there, though.
|
||||
|
||||
* src/truetype/ttgload.c (load_truetype_glyph): Fix error condition.
