Class description
Objects of this type represent renderbuffer objects, two-dimensional image buffers that can serve as framebuffer-attachments to user-created framebuffer objects.

Notes
Renderbuffer objects require OpenGL 3.0 or one of the GL_ARB_framebuffer_object or GL_EXT_framebuffer_object extensions.
