True that. The handling of context->render_offscreen and related
states is a mess (not to mention the bugs it has caused over time) :/

I guess my reservations have mostly to do with acquiring and
immediately releasing the context to restore the previous state,
although it looks like avoiding that dance would practically require
reimplementing context_acquire() inside context_restore() so meh...
