/**
 * Native bindings to the APPLE_framebuffer_multisample extension.
 * 
 * This extension extends the framebuffer object framework to enable multisample rendering.
 * 
 * The new operation RenderbufferStorageMultisampleAPPLE() allocates storage for a renderbuffer object that can be used as a multisample buffer. A
 * multisample render buffer image differs from a single-sample render buffer image in that a multisample image has a number of SAMPLES that is greater
 * than zero. No method is provided for creating multisample texture images.
 * 
 * All of the framebuffer-attachable images attached to a framebuffer object must have the same number of SAMPLES or else the framebuffer object is not
 * "framebuffer complete". If a framebuffer object with multisample attachments is "framebuffer complete", then the framebuffer object behaves as if
 * SAMPLE_BUFFERS is one.
 * 
 * The resolve operation is affected by calling ResolveMultisampleFramebufferAPPLE where the source is a multisample application-created framebuffer
 * object and the destination is a single-sample framebuffer object. Separate read and draw framebuffer object binding points are established to
 * facilitate the resolve.
 * 
 * Scissoring may be used in conjunction with ResolveMultisampleFramebufferAPPLE to resolve only a portion of the framebuffer.
 * 
 * Requires {@link GLES20 GLES 2.0}.
