Draping method for sources

The roads sources and railway sources are now draped when launching the simulations, such as the linear sources.

•In version 3.3 and earlier, theses sources were considered in XYZ in the simulation, where Z corresponds to the altitude of the ground. Their heights were added.

•In version 4.0, the height of the sources is "floating". It means that it is calculated when the simulation is launched.

For the volumic sources: theses sources have no Z, they are also draped when the simulation is launched. MithraSIG manages various cases to determine if a source is into a building, then what part of the volume is above the building, ...

For point sources: they have a variable Z, but calculated when the simulation is launched. As for the volumic sources, MithraSIG manages various cases: sources on building, on ground, ...

For facade sources: They are also draped when launching a simulation for consistency. Indeed, if the altitude of a building is modified, the height of the source is not updated in the interface.
