/**
* 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}.
