/**
 * Native bindings to the EXT_blend_minmax extension.
 * 
 * Blending capability is extended by respecifying the entire blend equation. While this document defines only two new equations, the {@link #glBlendEquationEXT BlendEquationEXT}
 * procedure that it defines will be used by subsequent extensions to define additional blending equations.
 * 
 * The two new equations defined by this extension produce the minimum (or maximum) color components of the source and destination colors. Taking the
 * maximum is useful for applications such as maximum projection in medical imaging.
 * 
 * Promoted to core in {@link GL14 OpenGL 1.4}.
