Balance initial value set to "0" rather than "false". "False" is interpreted as 0 when decoded as a float, so there will be no effect here, but this expresses the intended logic better.

Fixed a longstanding bug that caused stereo channels to be flipped incorrectly.
...
This was due to the initial audio buffer write position being aligned to the middle of a 4 byte (2 byte left, 2 byte right) audio sample.
In multi-threaded mode, some sort of race condition caused this alignment to be fixed until audio playback was temporarily paused (via pausing, loading a state, etc.)
Audio playback should now be fixed and work consistently in all cases.

- Reworked logging system to support output to multiple outputs: files, stdout, stderr, and syslog (OutputDebugString on Windows, syslog on other systems).
...
- Added ordinal logging level: all, debug, info, error. Compiling with DEBUG defined is no longer necessary for debug logging. Be careful when logging debug level because it produces copious output.
- Fixed -enter-debugger options when compiled with SUPERMODEL_DEBUGGER.
- Command line parse errors no longer ignored; Supermodel will now exit.

Various SCSP improvements and code cleanup:
...
- Ported MAME's implementation
- Corrected FM sound for songs in VF3 that use it
- Music tempo now closer to real hardware thanks to emulating two SCSP chips.
- Add LegacySoundDSP config option for games with SCSP DSP glitches (ex. engine noises in Sega Rally 2, and loud garbage on Bahn's stage in Fighting Vipers 2)
- Renamed SysFPS to "SoundClock" (since raising this appears to adjust the sound frequency).

The translator map seems to work with paletted colour values too, and the result is not clamped. Colours are passed to the GPU as unsigned bytes to multiplying by 16 will overflow, so we do the logic in the shader. If we passed floats we could skip the shader logic.

When the translator map is enabled the colour values seem to use 4 bits, 0-16. Why not 0-31 I don't know. Anyway virtua on is overflowing these values for some of the smoke effects. For us the numbers were wrapping around. Clamping is enough to fix this. (Thanks model123)

Sutherland-Hodgeman clipping only works for planar primitives. Scud is rendering non planar quads and this breaks our algorithm a little when using the quad renderer. Stretching the near plane a few % is enough to fix it.

Fix the sky in harley in first person mode where pixels in the sky are culled when they shouldn't be with the quad renderer. Basically we were running out of precision in a rare corner case. Doing the maths with double precision and casting back to float was enough to fix the issue.

To calculate the mipmap value the opengl needs to calculate the difference in the texture coordinates between adjacent pixels. If there are no adjacent pixels the hw may need to spawn invisible fragments outside of the visible polygon. Our algorithm was culling these out so the mipamp calculation failed for edge pixels. Anyway this fixes quad rendering looking broken with the latest nvidia drivers.

Stretch the time the ping_pong bit flips a bit to bump writes into correct frame. Otherwise they end up getting written at like 99.8% of the frame and overlapping with the next.

Thanks to our anonymous contributor who managed to patch a model 3 game and run it on real h/w, we were able to obtain some timing values we had been long been missing for correct emulation. The h/w polls something called the ping_pong bit at start-up to sync the GPU with the CPU. Unfortunately we didn't have the correct values and just manually used some per game hacks to get games to run. This mostly worked, but some games were writing more or less frames than they should have been for a given time period. When the ping_pong bit flips at 66% of the frame time, games were writing data for a new frame, which meant writes were often straddling 2 separate frames. We aren't 100% sure if IRQ2 or the ping_pong bit is vblank.

Ocean hunter in the middle of the game is passing a few matrices with FLT_MAX inside them, which blows apart our near/far calculation. The hardware must have some method to sanitize the near/far for instance if you render something extremely close to the origin you will also blow apart any near/far calc.
