86d739cc85 DDS TextureCache: remove unused code to support non-persistent images 
- this didn't compile for Stuart on OSG3.2 and it's not used.

9d99f4ce30 Added DDS Texture Cache. 
This is a performance improvement that reduces the amount of frame pauses which are related to mipmap creation when the geometry (osg::Texture) is added to the scene graph within osg::Texture::applyTexImage2D_load

The texture cache is configured from FG as follows
- /sim/rendering/texture-cache/cache-enabled
- /sim/rendering/texture-cache/compress-transparent
- /sim/rendering/texture-cache/compress-solid
- /sim/rendering/texture-cache/compress

These properties are set via the SGSceneFeatures singleton.

When the texture cache is enabled it will auto convert files from any supported osg::Image format that can be read and store the resulting (compressed or raw) file in the texture cache.

The texture cache uses osg_nvtt to perform texture compression (and mipmap generation) if available. When not available simgear::effect::computeMipmap is used to make mimaps but compression isn't available.

The texture cache filename ends with .TIME.cache.dds where TIME is the hex modtime of the original file. As yet there isn't a clean way to maintain the texture cache to ensure that stale files are removed; and in fact this is quite difficult to do because of the dynamic nature of the cache.

The texture cache will be stored in download_dir/texture-cache unless --texture-cache is passed on the command line.

The UI has a single checkbox to turn the texture cache on or off.

ba9342cd4b Fix effects for MP models - ticket 2076 
https://sourceforge.net/p/flightgear/codetickets/2076/

Effects were being instantiated by the loader for
all models, rather than just simple .ac/.obj models.

61cc8d6c50 Fix exception when number of primitive sets not what assumed. 
This was something that happened when random vegetation was off, but tree shadows was on.

Adding random vegetation would then reliably cause an exception.

f05ff37560 Fix for assert with empty systems 
Empty subsystem groups didn’t set their init state correctly, leading
to an assert on post-init. Fix this and add a test for it.

14354090f9 Don't check for cloud movement every frame 
Under Basic Weather, the cloudfield is finite size and clouds
are shifted as the viewpoint changes.  Previously each cloud
was checked every frame to determine if it should be shifted.
Not this only occurs if the viewpoint has moved a non-trivial
distance.

Note that this is separate from the clouds moving due to the wind.

1fa77078fc Subsystems: bind/init/unbind on add/remove 
When adding/remove subsystems to a group which is already bound or
inited, transition the subsystem automatically. This removes the
need to manually transition the subsystem in various places in
Flightgear.
