/**
 * Native bindings to the MESA_framebuffer_flip_y extension.
 * 
 * This extension defines a new framebuffer parameter, {@link #GL_FRAMEBUFFER_FLIP_Y_MESA FRAMEBUFFER_FLIP_Y_MESA}, that changes the behavior of the reads and writes to the framebuffer
 * attachment points. When {@code GL_FRAMEBUFFER_FLIP_Y_MESA} is {@link GLES20#GL_TRUE TRUE}, render commands and pixel transfer operations access the backing store of each
 * attachment point with an y-inverted coordinate system. This y-inversion is relative to the coordinate system set when
 * {@code GL_FRAMEBUFFER_FLIP_Y_MESA} is {@link GLES20#GL_FALSE FALSE}.
 * 
 * Access through {@link GLES20#glTexSubImage2D TexSubImage2D} and similar calls will notice the effect of the flip when they are not attached to framebuffer objects because
 * {@code GL_FRAMEBUFFER_FLIP_Y_MESA} is associated with the framebuffer object and not the attachment points.
 * 
 * Requires {@link GLES30 GLES 3.0}.
