Render thread: no direct GL call while recording, even for empty uploads

Browse Source 
An empty CPU->VRAM rect fell through to glb_vram_transfer_in on the
emulation thread while the render thread owned the context; it is now
recorded like any other upload. A projected triangle whose record cannot
be reserved takes the context first.
