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.
