Before the NVTT upgrade, no DXT1a file would have been properly decoded:
they would all have been mistaken for a 8bpp greyscale due to a logic
issue in our code, which would have triggered a crash. I did not notice
the logic issue when performing the upgrade. As a result, decoding those
files now fails silently: their alpha bit will be ignored and they will
be handled as DXT1.
This patch fixes the logic and allows us to decode DXT1a properly, in
accordance with the format specifications. Currently, we do not use this
format.

Windows binaries built with toolset v140_xp.
Tested under Windows, Linux and macOS.
Includes a patch for building on musl Linux, contributed by voroskoi,
containing code by leper.
Use the opportunity to set native line endings in the NVTT bundle.

This was SVN commit r19111.
When textures.xml specifies format="alpha", the input is expected to be
an
8-bit greyscale PNG, and the output will be an 8-bit uncompressed
alpha-only DDS.
Add format override to CTextureProperties, to select between e.g.
GL_ALPHA
and GL_LUMINANCE for 8-bit textures.
This is needed so fonts can use the new texture system.

lib_errors.cpp: replace with status.cpp, adapt to needs at work
wutil: fix runtime warning reported via feedback box
config: merge CONFIG_PARANOIA and !CONFIG_FINAL into
CONFIG_ENABLE_CHECKS
add openmp, pointer_typedefs.h

the old debug_assert always ran and tested the expression, which slows
down release builds. wrapping them in #ifndef NDEBUG is clumsy. the new
ASSERT behaves like assert and ENSURE like the old debug_assert. Let's
change any time-critical but not-super-important ENSURE to ASSERT to
speed up release builds. (already done in bits.h and unique_range.h)
This was SVN commit r9362.
major refactor of wfilesystem - remove gotos and workaround for FAT file
times
replace more round_up of constants with Align<>
remove old unused allocators (STL aligned, matrix, some shared_ptr)
move allocator utils into separate headers.
remove lockfree, wterminal
avoid testing __cplusplus
This was SVN commit r9361.
. completely rewrite waio - use IOCP, add several hardcore
optimizations. now outperforms the
AS SSD and ATTO benchmarks when writing
. refactor file interface - use LIO_READ instead of 'r', allow access to
file descriptor.
. completely rewrite the IO wrapper. now much more simple, less CPU
overhead, adds
support for pre-issue/post-completion hooks and preallocation.
io::Run defaults to simple synchronous IO; use io::Parameters to get
asynchronous.
. add alignment.h with constants and Align() function template (more
efficient than
round_up for compile-time constants)
. add UniqueRange - similar to C++0x unique_ptr (emulated for C++03),
plus a
built-in size. avoids expensive thread-safe reference counting in
shared_ptr.
cleanup:
- move fat_time functions into archive_zip
- remove no longer needed io_align and block_cache
- reduce dependencies in sysdep/compiler (move parts to
code_annotation.h)
- move IOCP into separate file (reused by waio)
This was SVN commit r9350.
- use wrapper class instead of std::wstring (reduces mixing of
strings/paths; allows safe+easy join via operator/ and convenient
case-insensitive comparison via operator==, avoids NativePathFromString,
similar to boost::filesystem)
- NativePath -> OsPath
- add hash and To/FromJSVal for Path
- add TS_ASSERT_PATH_EQUALS
- replace _wfopen_s with sys_OpenFile
- remove obsolete SortFiles/Directories
