/**
 * Native bindings to the EXT_framebuffer_blit extension.
 * 
 * This extension modifies EXT_framebuffer_object 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.
 * 
 * Promoted to core in {@link GL30 OpenGL 3.0}.
