Compilation Issues with Curves

[mtszkarbowiak]

Issue description:

Declaring API field of any type of curve in a serializable type causes compilation errors.

Steps to reproduce:

Just create this script:

// Headers...
API_CLASS() class GAME_API MySadScript : public Script
{
API_AUTO_SERIALIZATION();
DECLARE_SCRIPTING_TYPE(MySadScript);

API_FIELD() BezierCurve<float> TheCurve;
}

Voila: The project doesn't compile anymore.

Flax version:

1.7.2
