aircraft that do not have 3d cockpit configured. Toggling is done with the
"c" key. Note also that for now, since the 3d models don't have a "small"
panel defined, the "s" key is disabled if "allow-toggle-cockpit" is true.
These are the updates for the View manager properties. Removed the last of
items (within the viewer/viewmgr) hard coded to view number. Added support
for per view configuration of ground level nearplane value. Tower views look
very nice with little or no z-buffer problem in the models. Pilot offset
dialog can be used to move eye in all views.
This is sufficient to keep the wings level in cruise at 3000 ft, 2200
RPM; the value will have to change as we make changes to the model.
Note that a stock Cessna 172 does not have an aileron-trim wheel
inside the cockpit; to set the trim, you actually bend a sheet of
metal by hand when the plane is on the ground.
Andy's virtual-panel support. This will give a first taste of flying
with a 3D cockpit, but there are many caveats:
1. Clicking on the instruments doesn't work (waiting for a fix from
Andy).
2. The instruments rotate with the 3D cockpit but they don't tilt with
it (also waiting for a fix from Andy).
3. The orientation is incorrect when the view is not straight-forwards
and the plane is not flying level (waiting for a fix from me, but I
don't understand matrix math well enough).
4. The 3D interior is fairly ugly right now.
