Draft: Apply alignments to the geometry as TGeoPhysicalNodes before conversion to Geant4
Apply alignments as TGeoPhysicalNodes before invoking the conversion to Geant4 geometry. This fix does NOT work with the ROOT and DD4hep version in LCG up to 105c,as it requires:
In ROOT (https://github.com/root-project/root/), commits 0dc3985d0c2cf456277be4563530a914e5c60b0e and c33e6a4d897ac1dfe7a80c9985c485d90d09be07.
In DD4hep (https://github.com/AIDASoft/DD4hep/), commit 058f51694ae41659088fb15f591c8040cd6e3d95
