Subject: [PATCH] Track and display frame counts during lock

Add m_lastLockFrameCount and m_lockPaintFrameCount, compute frames
painted while the screen was locked and log the values. Show frame
counts in the lock info overlay, record frame count at lock, and reduce
the lock info font size for better layout.
