dc3f2980db Removes FMA check for matrix multiplication 
Removes preprocessor check for FMA instructions in matrix multiplication functions.
This simplifies the code and relies on the compiler's ability to optimize the
code based on available hardware support. The assumption is that modern
compilers will automatically utilize FMA instructions if available, and fall
back to alternative implementations if not.

```

Only the 'sufficient additional overloads' of `fmod` are guaranteed to be in `std`. Since this is clearly intended to call the (float, float) overload, explicitly cast `((green - blue) / delta)` (which is a `double`) to `float` and call the name in `std` as suggested by the diagnostic.

5be521ad2c Refactors Vector operations for type safety 
Ensures type safety in Vector2, Vector3, and Vector4 operations by using static_cast(0) instead of relying on implicit conversions.
This prevents potential issues with different numeric types.

Adds from_im_vec2 and from_im_vec4 methods for creating vectors from ImVec2/ImVec4 types.

a3b6435bac Merge pull request #52 from orange-cpp/feature/more_traits 
Adds engine traits for projectile prediction

0abfeba109 Adds engine traits for projectile prediction 
Implements engine-specific traits for projectile and target position prediction.
Each trait encapsulates logic tailored to a specific game engine (IW, OpenGL, Unity),
accounting for engine-specific coordinate systems and calculations.
This allows for accurate projectile prediction across different game environments.

5c9b36a03c Refactors target position prediction 
Moves target prediction logic into engine traits, improving modularity.

This change consolidates target position prediction within the engine traits,
allowing for a more flexible and maintainable design.

This eliminates redundant code and simplifies the core prediction engine by
delegating target movement calculations to the appropriate trait.

0e403f916d Adds direct pitch angle calculation 
Implements a direct pitch angle calculation for scenarios with zero gravity, ensuring accurate projectile trajectory predictions in such conditions.

Also marks several methods as noexcept for better performance and exception safety.

d66ccf2f74 Refactors projectile prediction engine 
Migrates projectile prediction logic to leverage engine traits for improved flexibility and testability.

This change decouples core prediction algorithms from specific engine implementations, allowing for easier adaptation to different game engines or simulation environments.

6c5c86b850 Refactors projectile prediction engine 
Refactors the projectile prediction engine by introducing an interface
and making the legacy implementation more flexible.

The legacy engine is updated to allow for coordinate system customization
through virtual methods, enabling usage in different game environments.

Also introduces vcpkg support for easier dependency management and adds boost-asio as a dependency.

0fe5b6b7a1 Enables legacy code compilation 
The changes encapsulate the matrix tests within an `#ifdef` block, allowing conditional compilation based on whether `OMATH_ENABLE_LEGACY` is defined. This enables the legacy code to be compiled only when needed.

## 🤝 Contributing to OMath or other Orange's Projects
### ❕ Prerequisites
- A working up-to-date OMath installation
- C++ knowledge
- Git knowledge
- Ability to ask for help (Feel free to create empty pull-request or PM a maintainer
in [Telegram](https://t.me/orange_cpp))
### ⏬ Setting up OMath
Please read INSTALL.md file in repository
### 🔀 Pull requests and Branches
In order to send code back to the official OMath repository, you must first create a copy of OMath on your github
account ([fork](https://help.github.com/articles/creating-a-pull-request-from-a-fork/)) and
then [create a pull request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/) back to OMath.
OMath developement is performed on multiple branches. Changes are then pull requested into master. By default, changes
merged into master will not roll out to stable build users unless the `stable` tag is updated.
### 📜 Code-Style
The orange code-style can be found in `.clang-format`.
### 📦 Building
OMath has already created the `cmake-build` and `out` directories where cmake/bin files are located. By default, you
can build OMath by running `cmake --build cmake-build/build/windows-release --target omath -j 6` in the source
directory.

Thanks to everyone who made this possible, including:
- Saikari aka luadebug for VCPKG port.
- Saikari aka luadebug for VCPKG port and awesome new initial logo design.
- AmbushedRaccoon for telegram post about omath to boost repository activity.
- Billy O'Neal aka BillyONeal for fixing compilation issues due to C math library compatibility.
And a big hand to everyone else who has contributed over the past!

OMath is a 100% independent, constexpr template blazingly fast math library that doesn't have legacy C++ code.
It provides the latest features, is highly customizable, has all for cheat development, DirectX/OpenGL/Vulkan support, premade support for different game engines, much more constexpr stuff than in other libraries and more...

- **Versatility**: Includes a wide array of mathematical functions and algorithms.
- **Ease of Use**: Simplified interface for convenient integration into various projects.
@@ -21,57 +52,45 @@ Oranges's Math Library (omath) is a comprehensive, open-source library aimed at
- **Collision Detection**: Production ready code to handle collision detection by using simple interfaces.
- **No Additional Dependencies**: No additional dependencies need to use OMath except unit test execution
- **Ready for meta-programming**: Omath use templates for common types like Vectors, Matrixes etc, to handle all types!
- **Engine support**: Supports coordinate systems of Source, Unity, Unreal, IWEngine and canonical OpenGL.
- **Cross platform**: Supports Windows, MacOS and Linux.
- **Algorithms**: Has ability to scan for byte pattern with wildcards in PE files/modules, binary slices, works even with Wine apps.

## ❔ Usage
Simple world to screen function
```c++
TEST(UnitTestProjection, IsPointOnScreen)
{
const omath::projection::Camera camera({0.f, 0.f, 0.f}, {0, 0.f, 0.f} , {1920.f, 1080.f}, 110.f, 0.1f, 500.f);
<br>
const auto proj = camera.WorldToScreen({100, 0, 15});
EXPECT_TRUE(proj.has_value());
}
```
