Sorry, please ignore my previous comment. It was submitted prematurely.

Actually digging around context.c has led me to see one case where
context->current_fbo can remain NULL.
> From context_apply_fbo_state(), if !context->render_offscreen,

context->current_fbo = NULL;
context_bind_fbo (context, GL_FRAMEBUFFER, NULL);

In context_bind_fbo(),
f = 0;                                             
if (context->fbo_read_binding == f && context->fbo_draw_binding == f) return;   
context->fbo_read_binding = f;                                      
context->fbo_draw_binding = f;
gl_info->fbo_ops.glBindFramebuffer(target, f);

The above code doesn't touch context->current_fbo, does it? Unless I'm mistaken
and somewhere in gl_info->fbo_ops.glBindFramebuffer(target, f) sets it somehow?
