/**
 * Native bindings to the NV_framebuffer_blit extension.
 * 
 * This extension modifies OpenGL ES 2.0 by splitting the framebuffer object binding point into separate DRAW and READ bindings. This allows copying
 * directly from one framebuffer to another. In addition, a new high performance blit function is added to facilitate these blits and perform some data
 * conversion where allowed.
 * 
 * Requires {@link GLES20 GLES 2.0}.
