Add some values to the SimulatorFeatures cap's OpenSimExtras section:

SimulatorFPS: The actual optimal FPS of the simulator, un-fudged
SimulatorFPSFactor: The fudge factor that is applied to the stats sent to the viewer
SimulatorFPSWarnPercent: The percentage below which a lag meter should go to amber
SimulatorFPSCritPercent: The percentage below which a lag meter should go to red
To display the real values, a viewer would divide the reported FPS by the SimulatorFPSFactor and use that to calculate the percentage of SimulatorFPS. E.g. reported is 55fps, SimulatorFPSFactor is 5.0 and SimulatorFPS is 11.
