This is needed for the docs generator to generate all the docs for the
posix package, if it is imported like it was on Windows it would
generate docs for the Windows version of the package which has much less
symbols exposed.
Translation matrices use the w components of the matrix to apply the
transform, and thus only work when the w component is 1. In the
original raymath implementation, the multiplication is done manually
and adds the translation components directly to the result, as if w is
1, but in the Odin binding this is done with a matrix multiplication.
However, the w component is set to 0 instead of 1, resulting in the
translation not being applied.
afed3ce removed the sys/unix package and moved over to sys/posix, it has
new bindings for the pthread APIs but should have been equivalent (not).
8fb7182 used `CANCEL_ENABLE :: 0`, `CANCEL_DISABLE :: 1`, `CANCEL_DEFERRED :: 0`, `CANCEL_ASYNCHRONOUS :: 1` for Darwin, while the
correct values are `1`, `0`, `2` and `0` respectively (same mistake was made for
FreeBSD in that commit).
What this meant is that the
`pthread_setcanceltype(PTHREAD_CANCEL_ASYNCHRONOUS)` was not actually
successful, but because the error wasn't checked it was assumed it was.
It also meant `pthread_setcancelstate(PTHREAD_CANCEL_ENABLE)` would
actually be setting `PTHREAD_CANCEL_DISABLE`.
The code in this PR restores the behaviour by now actually deliberately
setting `PTHREAD_CANCEL_DISABLE` and not setting
`PTHREAD_CANCEL_ASYNCHRONOUS` which was the previous behaviour that does
actually seem to work for some reason.
(I also fixed an issue in fmt where `x` would use uppercase if it was a
pointer.)
libstdc++'s |memcpy| and |memset| both state that their inputs should
never be a nullptr since this matches the C spec. Some compilers act on
these hints, so we shouldn't unconditionally call these as it would
signal to the compiler that they can't be nullptrs.
As an example, the following code will always call |do_something()|
when compiled with optimisations since GCC version 4.9:
```
void clear(void *ptr, int size) {
memset(ptr, 0, size);
}
void example(void *ptr, int size) {
clear(ptr, size);
if (ptr != nullptr) do_something();
}
```
