[pkg-fgfs-crew] Bug#760698: flightgear-data-aircrafts: SenecaII: incorrect fuel flow indication in the 3D cockpit

[Ludovic Brenta]

Package: flightgear-data-aircrafts
Version: 3.0.0-1
Severity: minor
Tags: patch

There is a discrepancy between the value of the
/engines/engine[...]/fuel-flow-gph and the indication on the fuel flow
gauge in the 3D panel.  The neeles indicate a value much higher than the
actual.  This is because the gauge (SenecaII/Instruments-3d/Faces3.rgb)
uses a nonlinear scale whereas SenecaII/Instruments-3d/FuelFlow.xml
specifies a linear relationship between fuel flow and the angle of the
needles.  Patch attached, replacing the linear relationship with a
nonlinear one using interpolation.

Changelog: 

* The scale of the fuel flow gauge is nonlinear; drive the needles accordingly.
