QuadTree relies on a bounding box to set up correctly.
ProxyNodes don't have a BB until the model is loaded,
causing the QuadTree to collapse if the DB loader can't
keep up with the STG loader.
Fix this by creating a default BB before the model
is loaded.
Using a weak pointer is the best way to ensure no invalid
pointer is used. This also fixes a possible crash in
simgear::canvas::Element::getParentStyle on destructing
canvas elements.
- check the catalog version explicitly when refreshing
- handle packages with distinct dir name / primary ID correctly
(requires an updated catalog XML format)
- rename failure code to status code, and add more to handle
cancellation.
- change caching of active Installs from Catalog to Root, to clarify
ownership
- expose download status on Install
- adjust Delegate signatures to pass more information
Add a 4th layer to the sun (next to disc, inner halo and outer halo). While the inner/outer halos change with atmosphere conditions, the new layer is supposed to represent the effect of blinding brilliance - ideally it adds a suitable ray structure to the sun. The effect is most prominent in space (where I'm most keen on seeing it admittedly) because there all atmospheric halo effects are absent and we end with a really unrealistic white disc.

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.
