Remove uses of .str(), .c_str() and some other methods of SGPath.
Pass SGPath directly where possible, or explicitly convert to the
appropriate 8-bit encoding.
* Fixed the trim on ground algorithm. Now JSBSim aircrafts should no longer be 'dropped' on the runway at start.
* Removed a correction on the propeller induced velocity that was giving erratic results when the aircraft aero velocity is very small.
* Various source comments updates.
Tolerate the case where a URL matching the exact FG version is
not found; lookup a generic URL, in the hope it supports our
version (additional changes will make this more likely)
The precipitation branch of the OSG scene graph is now centrally managed by the
scenery manager rather the precipitation manager itself. The scene graph
initialisation from the constructor has also been shifted into the new
FGPrecipitationMgr::sceneGraphSetup() function.
As the scenery manager's init() function is called twice on start up, two OSG
scene graph roots would be created. A number of scene graph branches would be
initalised on the first root, but then be lost as the second is created. This
fixes the precipitation branch, for example.
- The first place where indentation is fixed was really misleading, at
least.
- The added comment "'line' may end with an \r character [...]" just
clarifies something that has been there for ages, to avoid people
falling into the trap.
- don't duplicate the line buffer (array of char as well as
std::string), it is not useful here;
- don't corrupt (truncate) input lines longer than 2048 bytes: there is
no such limitation in the apt.dat v1000 format spec;
- fix comments handling: the apt.dat v1000 format spec states they must
start with *two* '#' characters.
- The first two lines of apt.dat have their own special syntax -> handle
them separately. Before this commit, the test "is the first character
an 'I' or an 'A'?" was done for *every* line of apt.dat, while it is
only relevant for the first one.
- Fix counting of the current line number (it was most of the time
0-based so far, which could be seen in error messages, because the
second line of apt.dat was absorbed without going through the common
code path where lines are normally read at the top of the while loop).
With this commit, line numbers in apt.dat are consistently counted
starting from 1.
