Test Build

This test build include three somewhat experimental features:

1. An "HDMI Clock" setting to compensate for the clock offset between the Beeb and the Pi, and also compensate for games that run with interlace off (i.e. 50.08Hz rather than 50Hz).

2. A "VSync" setting that is a debugging aid to let you see the position of the Pi's HDMI VSync compared to the Beeb's VSync. Useful to check the previous setting is correct.

3. A "Num Buffers" setting that changes the buffering strategy used in Modes 0..6:

• single buffering (minimal latency, but lots of potential for tearing and currently messes up the OSD)
• double buffering (typically an extra 20ms latency, but greatly reduces tearing)
• triple buffering (eliminates all tearing)
• quadruple buffering (overkill, never really needed)
