glIsFramebuffer returns GL_TRUE if framebuffer is currently the name of a framebuffer object. If
       framebuffer is zero, or if framebuffer is not the name of a framebuffer object, or if an error occurs,
       glIsFramebuffer returns GL_FALSE. If framebuffer is a name returned by glGenFramebuffers(), by that has
       not yet been bound through a call to glBindFramebuffer(), then the name is not a framebuffer object and
       glIsFramebuffer returns GL_FALSE.
