Version 0.4.1 - Scuba Circuit and Hypermiling

A hidden yet significant bug was brought to my attention, so I have rolled out the latest changes as a small 0.4 update.

Now, when you press Ctrl + F to show the suspension and tire forces, some extra details will be displayed above the virtual gauge cluster, in units determined by the unit setting for the speedometer:

• Power output (kW or bhp)
• Torque output (Nm or lb.ft)
• Instant fuel efficiency (L/100km or MPG)
• Average fuel efficiency (same as above)
• Throttle opening (including idle and auto-clutch)
• Brake and clutch input

Yes, you can now try your hypermiling skills in GDSim! :P You do not need to leave the details up for the average to be calculated; you can look it up any time.

I have included a new autocross layout I had prepared. Let's call it Scuba Circuit. :)  A different method of rendering the concrete barriers improved performance enough to grant including this extra-large layout, which neatly fits the dimensions of the entire lot.

Refinements to the simulation carry on; I've reduced the ABS slip threshold, added an altitude-based effect to engine and aerodynamic calculations (not very meaningful yet), and corrected a small mistake in the differential torque split.

NEW

• Extra HUD details when Show Forces (Ctrl+F) is activated
• New autocross layout - "scuba.png"
  • Accurate to scale (by aerial image) :)
  • Yardstick for determining the autocross lot size

FIXES

• Fixed unintended initial camera angle when switching to chase cam
• "Show Forces" cones now visible in the dark
• Alteration to differential torque split calculation
• Fixed a secret

IMPROVEMENTS / ADJUSTMENTS

• Autocross concrete barrier reimplemented as a multimesh (FPS+)
• Altitude now affects engine performance and aerodynamics
• Reduced ABS slip threshold
