This object allows easy use of setting up the framebuffer and or renderbuffer. The general idea is that you can set one of these up once for each type of operation you plan to do (to have a depth buffer or not.) Once configured, you tell it to start, perform drawing, and tell it to end. Anything you did during the drawing phase will be written to TexturesToAttach. In order to access more than the first buffer, you must use a shader and output the data to different buffers. In general, most systems allow 4-8 textures to be attached.

Redirect the drawing back to the regular framebuffer. Note, you should use GLUT.miWidth and GLUT.miHeight for the parameters here.
