814adf11de Note that radians is expected in glm_perspective()
The `fovy` parameter is expected in radians, which isn't mentioned anywhere in the docs. Causes unnecessary confusion. Might as well point it out.

c013bd462c Add LH & RH_NO perspective functions
This commit adds functions `glm_perspective_lh_no` and
`glm_perspective_rh_no` to the code. Unit tests are added and this
commit follows the new pattern of adding the a new file per
coordinate-system and clip-space tuple.

. Makefile.am updated
. removed test/glm_cmp project stub
. unit tests include naive implementations to as well as magic number
  ref-data generated by the corresponding GLM functions.

No tests run yet on Windows or Mac.

b3a18b8a15 Add glm_perspective_rh_zo function + tests
This commit adds the RH/ZO perspective function. It does so in the new
file `cam_rh_zo.h` and further refactors the LH variant into new file
`cam_lh_zo.h`. This creates some churn in the tests and configuration
files as new test files were added as well, and all these changes found
their way into the build files.

Tests passing on Linux.

1bce62c371 Add function glm_perspective_lh_zo
This commit adds the function `glm_perspective_lh_zo`, modelled on the
implementation of glm_perspective, but amended to provide a left-hand
coordinate system expected by DirectX, Metal and Vulkan (per the GLM
project's `glm/detail/setup.hpp`). It uses a clip-space of zero-to-one.

The function is tested against a longhand version of the algorithm it
seeks to implement as well as against the output of the GLM project's
`glm::perspectiveLH_ZO` function. This commit adds a new subdirectory
`test/glm_cmp` which contains a basic CMake file and `main.cpp`. An
interested user should link or copy or clone the GLM project into this
directory. The `main` function can be used to print the reference data
used so others can verify behaviour in the future, or add new literal
reference values.

5fa908602f simd/x86: fix -Wcast-align warnings (gcc/clang)
This modifies glmm_{load,store}3 functions to make the compiler assume
the v pointer is appropriately aligned for the type it is being cast to.
Not tested with CGLM_ALL_UNALIGNED, but it probably doesn't matter.

- `vec4` and `mat4` variables must be aligned. (There will be unaligned versions later)
- **in** and **[in, out]** parameters must be initialized (please). But **[out]** parameters not, initializing out param is also redundant
- All functions are inline if you don't want to use pre-compiled versions with glmc_ prefix, you can ignore build process. Just include headers.
- if your debugger takes you to cglm headers then make sure you are not trying to copy vec4 to vec3 or alig issues...

#### Note for experienced developers:
#### 📌 Note for experienced developers:
- Since I'm testing this library in my projects, sometimes bugs occurs; finding that bug[s] and making improvements would be more easy with multiple developer/contributor and their projects or knowledge. Consider to make some tests if you suspect something is wrong and any feedbacks, contributions and bug reports are always welcome.
#### Allocations?
#### 📌 Allocations?
`cglm` doesn't alloc any memory on heap. So it doesn't provide any allocator. You should alloc memory for **out** parameters too if you pass pointer of memory location. Don't forget that **vec4** (also quat/**versor**) and **mat4** must be aligned (16-bytes), because *cglm* uses SIMD instructions to optimize most operations if available.
#### Returning vector or matrix... ?
#### 📌 Returning vector or matrix... ?
**cglm** supports both *ARRAY API* and *STRUCT API*, so you can return structs if you utilize struct api (`glms_`).
#### Other APIs like Vulkan, Metal, Dx?

The types used are actually unions that allow access to the same data multiple ways. One of those ways involves anonymous structures, available since C11. MSVC also supports it for earlier C versions out of the box and GCC/Clang do if you enable `-fms-extensions`. To explicitly enable these anonymous structures, `#define CGLM_USE_ANONYMOUS_STRUCT` to `1`, to disable them, to `0`. For backward compatibility, you can also `#define CGLM_NO_ANONYMOUS_STRUCT` (value is irrelevant) to disable them. If you don't specify explicitly, cglm will do a best guess based on your compiler and the C version you're using.

Clipspace Option[s]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By starting **v0.8.3** cglm provides options to switch between clipspace configurations.
Clipspace related files are located at `include/cglm/[struct]/clipspace.h` but
these are included in related files like `cam.h`. If you don't want to change your existing
clipspace configuration and want to use different clipspace function like `glm_lookat_zo` or `glm_lookat_lh_zo`...
then you can include individual headers or just define `CGLM_CLIPSPACE_INCLUDE_ALL` which will iclude all headers for you.
1. **CGLM_CLIPSPACE_INCLUDE_ALL**
2. **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
3. **CGLM_FORCE_LEFT_HANDED**
1. **CGLM_CLIPSPACE_INCLUDE_ALL**:
By defining this macro, **cglm** will include all clipspace functions for you by just using
`#include cglm/cglm.h` or `#include cglm/struct.h` or `#include cglm/call.h`
Otherwise you need to include header you want manually e.g. `#include cglm/clipspace/view_rh_zo.h`
2. **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
This is similar to **GLM**'s **GLM_FORCE_DEPTH_ZERO_TO_ONE** option.
This will set clip space between 0 to 1 which makes **cglm** Vulkan, Metal friendly.
You can use functions like `glm_lookat_lh_zo()` individually. By setting **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
functions in cam.h for instance will use `_zo` versions.
3. **CGLM_FORCE_LEFT_HANDED**
Force **cglm** to use the left handed coordinate system by default, currently **cglm** uses right handed coordinate system as default,
you can change this behavior with this option.
**VERY VERY IMPORTANT:**
Be careful if you include **cglm** in multiple projects.
