Move sqlite source to a separate location, and build with
an intermediate library target. This permits us to set compile options
easier, including an important one, NDEBUG, which improves performance.
Sqlite 3.8.0.2 also includes an updated query planner which may improve
some queries, to be tested.
Allow for advanced animations using easing functions and adapters
for interpolating specific property types (eg. CSS colors).
Old behavior should not have changed.
Make subsystems create-able and removable from commands. Only some subsystems are supported so far, since many have non-default constructors or other complexities.
With this, change, it's possible to dynamically add and remove the traffic-manager at runtime, for example: fgcommand("add-subsystem", props.Node.new({ "subsystem": "traffic-manager", "name":"traffic-manager", "do-bind-init":1}));
Keep distro packagers happy by having the option to use the system's sqlite library instead of our bundled version. Set SYSTEM_SQLITE=1 when running cmake to use the system one.
Cache the parsed navigation and airport data in a binary file to reduce
startup times and memory consumption (since only referenced FGPositioned
elements are held in memory).
Data will be reimported when the mod-time of any input file is changed.
If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache
will be completely rebuilt, which takes approximately 30 seconds on
moderate hardware. (Future work may reduce this).
Separate other init functions from position init, since they are unrelated, and made fg_init.cxx very complex. Next step will be brining some sanity to the position init logic :)
Don't detect libsvn without APR.
When installed, enable libsvn support by default (same as for automake).
When enabled, provide libsvn to fgfs.
gitignore temporary CMake files
HAVE_CULLSETTINGS_CLEAR_MASK was not set, so a program to test
CLEAR_MASK was added. The Posix timer function clock_gettime is in
librt on Fedora, and probably on other systems too.
