DefaultTypePool requires JIT compilation

[morgoth990]

I'm compiling the library in a project without JIT compilation.
On an older version everything was working fine but now I'm receiving an exception in DefaultTypePool.Creator.

private static readonly Func<T> Creator = Expression.Lambda<Func<T>>(Expression.New(typeof(T))).Compile();

public object Get()
{
    lock (_pool)
    {
            if (_pool.Count > 0)
            {
                return _pool.Dequeue();
            }
    }
    return Creator();
}

The Creator is compiling at runtime but without JIT compilation can't work.
Is the Creator needed?
Can't DefaultTypePool.Get() just return new T() ?

You can implement IPool yourself and pass an instance of it to the Tess constructor. I don't know if using JIT or not is detectable to remove this code from the DefaultTypePool at compile time and return new T() instead, I can accept a PR if you find a way to do that.

Just read your issue again, I'm also not sure why Creator can't be replaced with new T().

I have tested some cases with hundreds of complex contours and seem to work fine without any noticeable performance changes

Compiling this library for Unity on WebGL causes issues because of the Pool class.

I am in this repos for different reasons, but also working in a Unity WebGL project. Have not seen this problem yet, but likely it might be aggressive stripping. Did you try to manually inform the compiler to keep some of the classes? The same can happen if you add a SphereCollider with code only for example.
