Change the subsystem-group and manager code to use shared-ptr references
to subsystems, instead of holding a raw pointer. Hence the manager becomes
the owning ref to most subsystems.
Slave objects can now rotate around two axis to always track the
target - even when it is outside the plane perpendicular to the
lock-axis of the root object. This allows for example animating
levers with non-parallel axis of rotation connected with a rod.
Check explicitly for the 'no channels' case and
sleep instead, to avoid busy-waiting. (This is a work-
around, the underlying issue still be be traced)
- Update clipping rect if canvas view or texture size
changes.
- Add new property "clip-frame" to specify coordinate
frame for "clip" coordinates. Coordinates can be
global, relative to the parent or relative to the
element itself.
- refactor code used multiple times spread over sg/fg into
one single location.
- allow aborting requests.
- Provide two common request types:
* FileRequest: Save response into file
* MemoryRequest: Keep resonse in memory (std::string)
- extend HTTP::Client interface:
* urlretrieve: Save url to file (shortcut for making a
FileRequest)
* urlload: Get respons into memory (shortcut for making
a MemoryRequest)
Windows handling of ::rename differs from POSIX when the new name
exists. Check for this case on Windows and remove the file manually.
(This allows a work-around in SVNDirectory to be removed)
Bug 1190, fix route-manager -> GPS activation on Windows
(and probably a couple of unrelated issues).
SGPropertyChangeCallback was missing a suitable copy-constructor,
leading to incorrect behaviour on compilers where the operation
is not elided. Such as MSVC.
Test result of GetLastError so we don't log a warning in the
'nothing matched' case. Makes early startup logging much
more pleasant, especially when scanning aircraft dirs.
Encountered while testing v850 airports; some airports
generate materials with no tris, and hence no indices.
This causes a divide-by-zero when computing the index stride.
Detect this, and convert the BTG reader to throw exceptions
in error conditions, and to catch this and report the
appropriate result code.
This is some initial pieces to synchronise other pieces of base
data than scenery via the sync mechanism. An additional sync slot is
added to avoid scenery or other data blocking each other.
