libass-0.16.0

[Bruce Dubbs]

New minor version.

[Bruce Dubbs]

libass (0.16.0)

• Fix missing -framework options in libass.pc on macOS
• Fix missing GDI or DirectWrite options in libass.pc on Win32
• Fix crashes with fonts missing Postscript names and without one being synthesised by the font provider
• Fix crashes on negative fontsizes and some overflows
• Fix a rare memory leak introduced in 0.13.0
• Fix minimum dependency versions in configure and our pc-file
• Fix our public headers for use with GCC versions between 3.1.0 and 4.5.0 (was a regression introduced in 0.15.0)
• x86: Fix potential buffer over-read by 16 bytes with AVX2 assembly when large tiles are not enabled (the default)
• x86: Fix PIC flags not being interpreted by the assembler, breaking the asm-enabled build setup on NetBSD and OpenBSD. On 32-bit x86, if the toolchain requires PIC objects and relies on compiler defaults to get PIC implicitly, you need to pass --with-pic to configure to ensure NASM always produces PIC objects
• x86: Fix AVX support not being detected on non-Intel CPUs and some VMs
• x86: Fix CPUID being used on CPUs not supporting the instruction (<= i486) and the way it is used for CPUs with less than 7 CPUID-leafs which could lead to crashes due to illegal instructions
• MS Windows-only issue: Fix crashes with FreeType >= 2.11.1 on Win32 when rendering strikethrough or underline
• Improve \iclip quality
• Improve quality of very small outlines
• Switch to wyhash for much better cache performance
• Propagate ZWJ/ZWNJ effects across glyph run boundaries
• Do not depend on compiler-specific defines to actually use built assembly
• Expand documentation and fix mistakes in it
• configure now errors out if an explicitly requested feature is unavailable
• MS Windows-only issue: ease linking against static/shared GNU FriBidi
• Add ASS_FEATURE_WHOLE_TEXT_LAYOUT to apply bidi, shaping and \fay to the entire unsplit event text. The non-portable Encoding=-1 mode always behaves as if the feature were enabled
• MS Windows-only issue: add support for arbitrary Unicode paths; see documentation of related functions for details
• Improve VSFilter compatibility
  • Do not treat format lines using Actor in place of Name as custom format lines. The former is used by VSFilter itself, the latter by Aegisub
  • Run bidi and shaping on each glyph run separately by default
  • Match VSFilter's \fsp effects on bidi and shaping
  • Match VSFilter's \fay behaviour
  • Support non-Unicode font cmaps when Win32 API or iconv is available and can convert to the relevant encoding
  • Treat empty clip outlines as if everything was outside the clip not inside (was a 0.14.0 regression)
  • Parse integer parameters of override tags more like VSFilter
