Word description Copies the rectangular region from-fb-rect to to-fb-rect. If depth? is true, depth values are also copied, and if stencil? is true, so are stencil values. If the rectangle sizes do not match, the region is scaled using nearest-neighbor or linear filtering based on filter.
Notes This word requires OpenGL 3.0 or one of the GL_ARB_framebuffer_object or GL_EXT_framebuffer_blit extensions.
