24e417107b ci: initial support of meson and emscripten
It seems that meson only supports emscripten as a compiler to wasm at present, wasi-sdk support is not completed yet, so this only adds ci build scripts for emscripten.

009405adcd wasm: prefer pmin/pmax
According to [emscripten](https://emscripten.org/docs/porting/simd.html) and [v8](b6520eda5e/src/compiler/backend/x64/code-generator-x64.cc (L2661-L2699)), `[f32x4|f64x2].[min|max]` compiles to much more instructions than `[f32x4|f64x2].[pmin|pmax]`.
It is defined in [spec](https://github.com/WebAssembly/spec/blob/main/proposals/simd/SIMD.md#floating-point-min-and-max) that the difference between pmin/pmax and min/max is NaN-propagating behavior, and the equivalent to the x86 `_mm_min_ps`/`_mm_max_ps` is pmin/pmax in [v8](b6520eda5e/src/compiler/backend/x64/code-generator-x64.cc (L2740-L2747)).
This should make functions with min/max faster on webassembly, and align with the existing behavior with x86 sse.

Andrei Alexeyev
2724620d83 more robust __builtin_assume_aligned detection
__builtin_assume_aligned is available since GCC 4.7, but __has_builtin
was added much later. Check for the GCC version if __has_builtin is not
available.

Users can also define CGLM_HAVE_BUILTIN_ASSUME_ALIGNED to either 1 or 0
to explicitly enable/disable the use of __builtin_assume_aligned. Meson
will do it automatically (by performing a configure-time test).

Check for builtin before using it

Ned Loynd
f4c9ddf530 Check for builtin before using it

#### Use CMake to build for WebAssembly
Since math functions like `sinf` is used, this can not be targeted at `wasm32-unknown-unknown`, one of [wasi-sdk](https://github.com/WebAssembly/wasi-sdk) or [emscripten](https://github.com/emscripten-core/emsdk) should be used.
Should note that shared build is not yet supported for WebAssembly.
For [simd128](https://github.com/WebAssembly/simd) support, add `-msimd128` to `CMAKE_C_FLAGS`, in command line `-DCMAKE_C_FLAGS="-msimd128"`.
For tests, the cmake option `CGLM_USE_TEST` would still work, you'll need a wasi runtime for running tests, see our [ci config file](.github/workflows/cmake-wasm.yml) for a detailed example.
##### Use CMake and WASI SDK to build for WebAssembly
```bash
$ cmake .. \
-DCMAKE_TOOLCHAIN_FILE=/path/to/wasi-sdk-19.0/share/cmake/wasi-sdk.cmake \
-DWASI_SDK_PREFIX=/path/to/wasi-sdk-19.0
```
Where `/path/to/wasi-sdk-19.0/` is the path to extracted [wasi sdk](https://github.com/WebAssembly/wasi-sdk).
In this case it would by default make a static build.
##### Use CMake and Emscripten SDK to build for WebAssembly
```bash
$ emcmake cmake .. \
-DCMAKE_EXE_LINKER_FLAGS="-s STANDALONE_WASM" \
-DCGLM_STATIC=ON
```
The `emcmake` here is the cmake wrapper for Emscripten from installed [emsdk](https://github.com/emscripten-core/emsdk).

2d axis aligned bounding box (AABB)
================================================================================
Header: cglm/aabb2d.h
Some convenient functions provided for AABB.
**Definition of aabb:**
cglm defines an aabb as a two dimensional array of vec2's.
The first element is the **min** point and the second one is the **max** point.
If you have another type e.g. struct or even another representation then you must
convert it before and after calling a cglm aabb2d function.

rotate existing transform matrix around Z axis by angle and axis
rotate existing transform matrix around given axis by angle at ORIGIN (0,0,0)
**❗IMPORTANT ❗️**
If you need to rotate object around itself e.g. center of object or at
some point [of object] then `glm_rotate_at()` would be better choice to do so.
Even if object's model transform is identiy, rotation may not be around
center of object if object does not lay out at ORIGIN perfectly.
Using `glm_rotate_at()` with center of bounding shape ( AABB, Sphere ... )
would be an easy option to rotate around object if object is not at origin.
One another option to rotate around itself at any point is `glm_spin()`
which is perfect if only rotating around model position is desired e.g. not
specific point on model for instance center of geometry or center of mass,
again if geometry is not perfectly centered at origin at identity transform,
rotation may not be around geometry.

API documentation
📚 API documentation
================================
Some functions may exist twice,
once for their namespace and once for global namespace
to make easier to write very common functions
**cglm** provides a few APIs for similar functions.
For instance, in general we use :code:`glm_vec3_dot` to get dot product
of two **vec3**. Now we can also do this with :code:`glm_dot`,
same for *_cross* and so on...
* 📦 **Inline API**: All functions are inline. You can include **cglm/cglm.h** header
to use this API. This is the default API. `glm_` is namespace/prefix for this API.
* 📦 **Call API**: All functions are not inline. You need to build *cglm* and link it
to your project. You can include **cglm/call.h** header to use this API. `glmc_` is namespace/prefix for this API.
The original function stays where it is, the function in global namespace
of same name is just an alias, so there is no call version of those functions.
e.g there is no func like :code:`glmc_dot` because *glm_dot* is just alias for
:code:`glm_vec3_dot`
And also there are also sub categories:
By including **cglm/cglm.h** header you will include all inline version
of functions. Since functions in this header[s] are inline you don't need to
build or link *cglm* against your project.
* 📦 **Array API**: Types are raw arrays and functions takes array as argument. You can include **cglm/cglm.h** header
to use this API. This is the default API. `glm_` is namespace/prefix for this API.
* 📦 **Struct API**: Types are union/struct and functions takes struct as argument and return structs if needed. You can include **cglm/struct.h** header
to use this API. This also includes **cglm/cglm.h** header.`glms_` is namespace/prefix for this API but your can omit or change it, see struct api docs.
* 📦 **SIMD API**: SIMD functions and helpers. `glmm_` is namespace/prefix for this API.
But by including **cglm/call.h** header you will include all *non-inline*
version of functions. You need to build *cglm* and link it.

Call API
================================
Call API is pre-built API for making calls from library. It is built on top of the array api. **glmc_** is the namespace for the call api.
**c** stands for call.
You need to built cglm to use call api. See build instructions (:doc:`build`) for more details.
The functions except namespace **glmc_** are same as inline api. See ( :doc:`api_inline_array` ) for more details.
📌 In the future we can define option to forward inline functions or struct api to call api.

Array API - Inline (Default)

This is the default API of *cglm*. All functions are forced to be inlined
and struct api, call api uses this inline api to share implementation.
📌 Call api is also array api but it is not inlined.
In the future there may be option to forward struct api to call api instead of inline api to reduce binary size if needed.

Struct API
================================
Struct API is alternative API to array api to use **cglm** with improved type safety and easy to use.
Since struct api is built top of array api, every struct API is not documented here.
See array api documentation for more information for individual functions.
By default struct api adds `s` suffix to every type name e.g. vec3s, mat4s, versors etc.
Also struct api `s` suffix to namespace e.g. `glms_vec3_add`, `glms_mat4_mul` etc.
By starting v0.9.0, struct api namespace is configurable. We can omit **glms_** namespace or
even change it with custom name to move existing api integrations to **cglm** more easliy...
We can also add **s** to function names if we want e.g. `glms_vec3_add()` -> `vec3_add()` or `vec3s_add()`.
By including **cglm/struct.h** header you will include all struct api. It will also include **cglm/cglm.h** too.
Since struct apis are inline you don't need to build or link *cglm* against
your project unless if you want to use pre-built call-api too.
Struct API is built top of array api. So you can mix them.
Use **.raw** union member to access raw array data to use it with array api.
Unlike array api ([0], [1], [0][0] ...), it is also possible to use struct api
with **.x**, **.y**, **.z**, **.w**, **.r**, **.g**, **.b**, **.a**, **.m00**, **m01**...
accessors to access individual elements/properties of vectors and matrices.

Configuring the Struct API:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To configure the Struct API namespace, you can define the following macros before including the cglm/struct.h header:
- **CGLM_OMIT_NS_FROM_STRUCT_API**: omits CGLM_STRUCT_API_NS (`glms_`) namespace completely if there is sub namespace e.g `mat4_`, `vec4_` ... DEFAULT is not defined
- **CGLM_STRUCT_API_NS**: define name space for struct api, DEFAULT is **glms**

It's a good idea to set up your config macros in build settings like CMake, Xcode, or Visual Studio. This is especially important if you're using features like Modules in Xcode, where adding macros directly before the **cglm** headers might not work.

Options
🛠️ Options
===============================================================================
A few options are provided via macros.
❗️ IMPORTANT ❗️
It's a good idea to set up your config macros in build settings like CMake, Xcode, or Visual Studio. This is especially important if you're using features like Modules in Xcode, where adding macros directly before the **cglm** headers might not work.
Alignment Option
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
As default, cglm requires types to be aligned. Alignment requirements:
By default, **cglm** requires types to be aligned with specific byte requirements:
vec3: 8 byte
vec4: 16 byte
mat4: 16 byte
versor: 16 byte
- vec3: 8 bytes
- vec4: 16 bytes
- mat4: 16 bytes (32 on AVX)
- versor: 16 bytes
By starting **v0.4.5** cglm provides an option to disable alignment requirement.
To enable this option define **CGLM_ALL_UNALIGNED** macro before all headers.
You can define it in Xcode, Visual Studio (or other IDEs) or you can also prefer
to define it in build system. If you use pre-compiled versions then you
have to compile cglm with **CGLM_ALL_UNALIGNED** macro.
Starting with **v0.4.5**, **cglm** offers an option to relax these alignment requirements. To use this option, define the **CGLM_ALL_UNALIGNED** macro before including any headers. This definition can be made within Xcode, Visual Studio, other IDEs, or directly in your build system. If using pre-compiled versions of **cglm**, you'll need to compile them with the **CGLM_ALL_UNALIGNED** macro.
**VERY VERY IMPORTANT:** If you use cglm in multiple projects and
those projects are depends on each other, then
**NOTE:❗️** If you're using **cglm** across multiple interdependent projects:
| *ALWAYS* or *NEVER USE* **CGLM_ALL_UNALIGNED** macro in linked projects
- Always or never use the **CGLM_ALL_UNALIGNED** macro in all linked projects to avoid configuration conflicts. A **cglm** header from one project could require alignment, while a header from another might not, leading to **cglm** functions accessing invalid memory locations.
if you do not know what you are doing. Because a cglm header included
via 'project A' may force types to be aligned and another cglm header
included via 'project B' may not require alignment. In this case
cglm functions will read from and write to **INVALID MEMORY LOCATIONs**.
- **Key Point:** Maintain the same **cglm** configuration across all your projects. For example, if you activate **CGLM_ALL_UNALIGNED** in one project, ensure it's set in the others too.
ALWAYS USE SAME CONFIGURATION / OPTION for **cglm** if you have multiple projects.
**❗NOTE:❗️**
For instance if you set CGLM_ALL_UNALIGNED in a project then set it in other projects too
While **CGLM_ALL_UNALIGNED** allows for flexibility in alignment, it doesn't override C's fundamental alignment rules. For example, an array like *vec4* decays to a pointer (float*) in functions, which must adhere to the alignment requirements of a float pointer (4 bytes). This adherence is crucial because **cglm** directly dereferences these pointers instead of copying data, and failing to meet alignment requirements can lead to unpredictable errors, such as crashes.
You can use `CGLM_ALIGN` and `CGLM_ALIGN_MAT` macros for aligning local variables or struct members. However, when dealing with dynamic memory allocation or custom memory locations, you'll need to ensure alignment requirements are met appropriately for those cases

To configure the Struct API namespace, you can define the following macros before including the cglm/struct.h header:

- **CGLM_STRUCT_API_NAME_SUFFIX**: define name suffix, DEFAULT is **empty** e.g defining it as #define CGLM_STRUCT_API_NAME_SUFFIX s will add s suffix to mat4_mul -> mat4s_mul

For instance :c:func:`glm_dot` is alias of :c:func:`glm_vec3_dot`,
alias means inline wrapper here. There is no call verison of alias functions

There are also functions for rotating *vec3* vector. **_m4**, **_m3** prefixes

computes refraction vector for an incident vector and a surface normal.
Calculates the refraction vector based on Snell's law. If total internal reflection
occurs (angle too great given eta), dest is set to zero and returns false.
Otherwise, computes refraction vector, stores it in dest, and returns true.
This implementation does not explicitly preserve the 'w' component of the
incident vector 'I' in the output 'dest', users requiring the preservation of
the 'w' component should manually adjust 'dest' after calling this function.
Parameters:
| *[in]* **v** *❗️ normalized ❗️* incident vector
| *[in]* **n** *❗️ normalized ❗️* normal vector
| *[in]* **eta** ratio of indices of refraction (incident/transmitted)
| *[out]* **dest** refraction vector if refraction occurs; zero vector otherwise

* If you need to rotate object around itself e.g. center of object or at

* Using `glm_rotate_at()` with center of bounding shape ( AABB, Sphere ... )
* would be an easy option to rotate around object if object is not at origin.
*
* One another option to rotate around itself at any point is `glm_spin()`
* which is perfect if only rotating around model position is desired e.g. not
* specific point on model for instance center of geometry or center of mass,
* again if geometry is not perfectly centered at origin at identity transform,
