New interpolation/animation system.
Inspired by jQuery.animate() properties can be interpolated using
different easing functions and specifying an animation duration.
Additionally animations can be chained to get table-based
animations like with the current SGInterpolator, or also create
looped animations or other more complicated curves.
Currently this system is not used yet, but it is intended to
replace SGInterpolator and allow more advanced animations of
eg. also colors, for example, for the canvas.

Collect properties from expression/condition trees.
Initial ground-work to support efficient updating of condition/expression results; allow collecting all the dependent property values from the hierarchy, so they can be observed. Also add a very small test-case for this.

cppbind: refactor to_nasal for better name lookup.
Using template parameter dependent name lookup it is
now possible to create to_nasal_helper overloads
for custom types and having them used for automatic
type conversion with binding methods/member on
nasal::Ghost objects.

cppbind: rework to allow binding nearly everything.
It is now possible to register all types of member function
and free functions as methods for nasal::Ghost objects.
The return value and arguments are converte automatically
to the required types.
Also usage is simplified by removing replacing the old
method and method_func with a single method function
which only needs a name for the method and something
callable.

Look for MSVC 3rdparty deps differently.
Check for the 3rdparty dir in the parent of build dir, not the parent of the source dir. For the recommended build layout, this is the same location, but for super-builds using fgmeta it's not (and the source tree should not be touched).
If this causes anyone issues, please let me know, since it's possible more flexibility is needed to set the path explicitly.

cppbind: Prepare for improved bindings.
- Improved Nasal/C++ bindings will follow. For now just test if
all compilers are happy with intended approach.
- Add to_nasal overload for std::map<std::string, T>.

Add optional user_data to Nasal C functions.
A user_data pointer and another pointer to an optional
deleter function is stored in unused parts of the naPtr
union. The previous behavior of extension functions does
not change. Only one additional boolean comparison is
required upon each function call to check whether user
data is available.
The levels at which page nodes are built is exposed by an
osg database pager option SimGear::SPT_PAGE_LEVELS which could
contain a blank separated list of levels where paging occurs.
Also the database pagers paths are searched for static lower
level of detail tiles in case they are available.
This defers loading the models into a paged lod node
that is evaluated at a later point in time. That should
help for memory problems with higher visibilities.

Command-manager supports functors.
Will be used to support native Nasal commands, which was tricky with pure function pointers before. Can also be used to avoid some trampoline functions in the code, but this can happen gradually.

Fix CanvasText horizontal alignment.
Don't reduce width of bounding box below character width
even if outline of rendered character is smaller. This
prevents trailing spaces from being ignored and also
fixes continuously chaging alignment (especially with

Add 'release' bindings to knob animation.
Currently this fires on button release, but also after any mouse-wheel movement (since they are sent as buttons). This feels slightly wrong, but can't decide how a spring-loaded know would work, when interacting via the mouse-wheel. Comments welcome.
