29d20b1703 Temporarily fix a crash and correctly free memory until I can sort out a
problem with the partial ssg tree freeing code.

9885169964 Working on hunting down a really awful memory leak. This arose out of a
misunderstanding over which section of code would be freeing tiles.  This
patch cleans up several things, but a little more work is still needed.

e66c57a7bb Patch from Erik Hofman to remove 'random' option for sound:
I back out this patch because it gives me 2~3 bonus fps, and it isn't
used now and probably won't be used in the future.

0c0b150661 Bernie Bright:
I've merged FGProps and FGTelnet so there is just a single property server.
I've left in the --telnet=port# command line option but it could be removed
if we wanted to.  The command line accepts two forms of the --props option.
The original (--props=medium,dir,hz,host,port#,style) and the shorter
--props=port#.  If you accept this change then src/Network/telnet.[ch]xx
can be removed from the cvs repository.

1d82339fd8 Patch from Julian Foad:
When the scroll bar slider is dragged, the list scrolls only far enough to see all items; only the arrow buttons can scroll it so far that the last item goes to the top of the view.
    Fix scroll bar proportional size: was wrong when the list was only a little longer than the visible area.
    Minor fixes such as "delete files[i];" -> "delete[] files[i];" (where the item being deleted is an array of characters) and removal of global variables.
    Smooth scrolling when dragging the slider: one item at a time, rather than one tenth of the list at a time.
    Fix a bug that would have occurred if instantiated with arrows=2.
    Sort properties primarily by name and then by numerical index order, rather than a simple ASCII string order.  E.g. "js[1]", "js[2]", "js[10]" rather than "js[1]", "js[10]", "js[2]".
    Avoid crashing if the selected property path does not exist; display an empty list instead.  This cannot happen when the property picker is working properly, but did happen due to missing indices prior to this patch, and could happen if the user is allowed to type a pathname, as in the http and telnet interfaces.
    Fix truncation of strings to PUSTRING_MAX: was wrong when string length was exactly 80.
    Fix: move the scroll bar to the top each time a new list is displayed.  It was left at its previous position, while the top of the new list was displayed, not corresponding to the slider.
    Use getDisplayName instead of duplicated code: gives a better decision on whether to display the index, and avoids invalid property paths being generated which would previously crash find_props().
    Replace unnecessary node lookups by name with direct access: tidier and more efficient.  E.g. "getValueTypeString (node->getNode(name.c_str()))" -> "getValueTypeString (child)".

43d89cb8d6 Create a top-level branch in each tile for random objects with the
name "random-objects".

Put the random objects for each tile inside a top-level
ssgRangeSelector with a maximum range of 20km.  This saves a lot of
range tests for distant tiles, and gives about a 10% framerate boost
on my card at 1000ft AGL (possibly more on faster cards).

8244b210fa Give up on the idea of using a singleton dummy bounding sphere;
instead, use a separate dummy bounding sphere for each triangle and
each tile, with the actual bounds, to make sure that objects are
always added when they should be in sight.

27158525a9 Restructure the way tile freeing is handled. When a tile is removed from
the tile cache it's ssg elements are disconnected from the main ssg scene
graph, and then the tile is thrown on the end of a delete queue.  The
tilemgr->update() routine runs every frame.  It looks at this queue and if
it is non-empty, it incrementally frees the compents of the first tile
on the queue.  When the tile is completely free it is removed from the queue.

The amount of time to free the memory for even a single tile can be quite
substantial, especially with the increased overhead of dynamic/random
ground objects.  This change allows the system to spread the work of freeing
tile memory out over many frames so you don't get a noticable single frame
hit or stutter.

e7e576055f Added a new range-selector layer above each tile. That way, by

range.

1c35d89eb4 Fix a problem with the culling of out-of-range random objects. When
the triangles containing the objects were out of the view Frustum,
they were never traversed by ssg (and thus, never culled).  Now, every
200 frames, do a pass through the whole scene graph with cull-testing
disabled and without drawing anything; that will allow random-objects
to be collected incrementally.

6ac85b8625 Fixed a bug in FlightGear.py. Splitting name,value,type using whitespace
failed on /sim/time/gmt-string because the raw value contains an embedded
space.  Now I use a regex instead of a plain split().  I also removed the
view_next and view_prev functions.  These will have to be replaced with
command properties.

I've also added a FGFSDemo.py script which is a python version of David's java program.
