Interface GLLoadFunc

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface GLLoadFunc
GLLoadFunc relies on preview features of the Java platform:
Programs can only use GLLoadFunc when preview features are enabled.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
The OpenGL loading function.

// loads OpenGL compatibility profile
if (GLLoader.load(GLFW::getProcAddress, true) == null)
