For Windows, default file mode is TEXT.
If binary files should be created _O_BINARY shall be or'ed to the open
flags. This is not necessary on *nixes.
Introduce a SGBinaryFile as extension to SGFile which adds the flag
upon construction on Windows.
This should keep existing behaviour for all other usages of SGFile.
Let terrasync use the http repository if
/sim/terrasync/http-server == "automatic"
resolve DNS NAPTR RR for terrasync.flightgear.org with service "ws20"
and flags "U". Pick one of the returned entries with lowest order
and preference. If more than one entry with the same order and
preference is returned, pick a random entry of those returned.
or if
/sim/terrasync/http-server != "automatic"
explicitly use the value of that property as the http server
if
/sim/terrasync/http-server is empty, fall back to the legacy
SVN repository

Enable compile and test by adding -D ENABLE_DNS=Yes to cmake flags
add a create-flag to the node() method of a PropertyObject,
defaulting to false to maintain existing behaviour.
This could be used to add a listener to a non-existing property
without having to write a dummy-value beforehand.
Usage:
myPropertyObject->node() returns the corresponding node or NULL if
does not exist or has not been accessed before.
myPropertyObject->node(true) returns the corresponding node, never NULL.
If the property does not exist, it will gets created.

The following patch sets the sun color to alpha=0 when
the sun is below the local horizon, removing the oddity
that the sun is seen 'through' the terrain when the terrain
at large distance is rendered by the skydome.
Stuart has improved the UniformCache approach, here are his
changes:
- We have a UniformCache so that each unique Uniform is only created once
- As part of the UniformFactory we also have a queue of listeners that are still to be added
- When the main thread sends an Update node visitor across the Effects,
all queued listeners are de-queued and added.
The effect system used Listeners on property nodes to get the values
for shader uniforms. These listeners get deleted by an osg thread
causing access to freed memory when this happens while the main thread
calls fireValueChanged.
This patch changes the update method to polling for scalar properties.
This isn't 100% threadsafe, too. But at least it does not crash anymore.
executing the fgcommand loadxml implicitely untied every previously
tied property if a property type was given in the property element.
That made it impossible to autosave aircraft data for tied properties.
This patch should fix this. It adds an inconsitency, though:
if a property with a given type is read in which has been tied to
before and the property types do not match, the property type in the
xml file will be ignored.
New feature for <condition> elements:
An (optional) element <precision> allows for fuzzy equals checks
example:
<condition>
<equals>
<property>/foo</property>
<value type="double">0.0</value>
<precision>0.1</precision>
</equals>
</condition>
This condition evaluates as true if /foo is within [-0.05..0.05]
(both inclusive)
The precision tag works for int, long, float and double propeties.
It has no meaning for bool properties. For string properties,
precision sets the length of the strings to compare.
version.h is generated by the build system for official builds of
FlightGear. To avoid complicating the life of regular developers,
especially on Windows, we set HAVE_VERSION_H if version.h is generated.
If that define is not set, we include this file instead, which provides
placeholder values instead.
Due to fingertrouble, I removed the check for _step == 0 which
this patch re-adds.
Also, make this function look more like a template by not using
0.0 - constants.
msdn article 737550 states that "the preferred method is to call the
bind function to associate a socket with a local IP address and then
join the multicast group. Although this order of operations is not
mandatory, it is strongly recommended".
Since binding to the multicast address seems to fail, let's try binding
to INADDR_ANY and joint thereafter.
This class and their source files visual_enviro.[h|c]xx were
unused since OSG transition. It's only functionality was to
keep a variable for the enable-state of rendering of precipitation.
This has now been moved to SGPrecipitation.

Improvements to the global 3D clouds system
- clouds now move with the wind
- bug causing cloud coverage to be less than it should have been fixed
- support for adding 3D clouds with an fg_command.

SGMisc<T>::normalizePeriodic(min,max,value) returned zero for
all values less than min.
Example:
A call of normalizePeriodic(0,twopi(),-pi()) returned zero
where the correct value would be 3*pi().
