Disable all FBO rendering and return to traditional, windowing-system controlled framebuffer NOTE: This is NOT an "unbind" for this specific FBO, but rather disables all FBO rendering.
This call is intentionally "static" and named "Disable" instead of "Unbind" for this reason. The motivation for this strange semantic is performance. Providing "Unbind" would likely lead to a large number of unnecessary FBO enablings/disabling.

NOTE : This function works correctly in debug build mode but always returns "true" if NDEBUG is is defined (optimized builds)

Free any resource bound to the "attachment" point of this FBO.
