gear movement. gearToggle() was sending either a 0 (not handled) or a 1.
Change gearToggle() so it sends either -1 and 1 so gearToggle() will work
again.
- to support "old-style" gear/flap control (operation as long as button
pressed/lever pushed -> b29/hurricane), let bindings not only report
up/down, but up (-1), stop (0), down (1).
- let controls.flapsDown() ignore "stop" so as to remain compatible with
prior behavior
- adapt all joysticks/aircraft (sigh)
- some minor cosmetics in joystick configs, such as indentation fixes
I'd like to suggest that the spoiler settings are set in the same way as the
flaps are now done i.e. via Nasal, so that specific spoiler settings can also
be defined in the aircraft set file.
It was only when I was about to change the keyboard bindings for the slats
control that I remembered that there wasn't already a mapping for them in
keyboard.xml. I've _not_ added a mapping for slats as this is a bit of a hot
topic atm but as I had already added a Nasal func for the slats in
controls.nas I've left that in there. It's a trivial bit of code but I don't
know if leaving it in there is a good idea as it's code that shouldn't ever
be called until there's a corresponding keyboard mapping.
/sim/input/selected/engine[n] properties. Also, new properties get
empty string values (which are boolean true in Nasal, maybe that
should be changed?), so test for numeric truth.
Move the "tip popup" code from view.nas to a new gui.nas module, and
make it generically useful.
Wire up flap steppings for the 747 as an example of per-aircraft
flaps.
Realtime-based property slewing, to eliminate dependence of trim and
view direction rates on frame rate.
