This patch fixes configure.ac so that when an alternate prefix location for simgear is specified, configure tests for the header file jpegfactory.hxx in that specific location only.
Erik Hofman:
This patch contains an update to net_ctrls.hxx that adds an extra 100 bytes
(or an equivalent of 25 (u)int32_t types) of reserved space. This could be
used to make the protocol forward and backward compatibel within a certain
scope. Be sure to read the instructions at the begining of the header file
when addinf new variables.
"play-audio-function" command. This function can be called from internal
code, from nasal scripts, or from external scripts to play a single one-off
wav file. File/audio data is loaded and unloaded on the fly automatically.
Create a queue of one-off wav files. Calling layer can request the system
to play any wav file. The request is thrown at the end of a play queue.
The queue is serviced sequentially so that queued wav files will no longer
overlap. When a sample is finished playing. It is removed from the queue
and deleted from memory. The next remaining request in the queue is then
played.
- Provide a Nasal interface to display simple text messages on the screen
like the ATC display. In fact, I copied the code from the ATCDisplay.cxx
and simply shifted it further down the screen.

TODO: Integrate the two pieces of code.
anything in the nav tree is valid or not.
- Fix an order problem between caching data values and searching for a new
station that could cause odd and unexpected and hard to reproduce results.
Added a convenience function to estimate the time to intercept the selected
radial give the current heading and speed. This can be useful to a flight
directory to compute the point to switch from armed to coupled mode at just
the right time so the pilot can roll out onto the desired heading on the
desired radial.
Add a first whack at estimating a ground track heading error (difference
between aircraft heading and ground track directon.) This needs more work
and testing.
