⚡ Drain GPU work on partial render frames

Browse Source 
Partial frames only flushed the Backbuffer, so tile GPU commands
queued until present_frame's flush_and_submit and stalled the
browser on large files. Submit the context each partial frame
without presenting Target or re-composing the tile atlas.
