OrthancMultiframeVolumeLoader and OrthancSeriesVolumeProgressiveLoader now implement IGeometryProvider so that the geometry reference can be switched (CT or DOSE, for instance) + VolumeImageGeometry::SetSize renamed to VolumeImageGeometry::SetSizeInVoxels + prevent text layer update if text or properties do not change + a few stream operator<< for debug (Vector, Matrix,...) + fixed memory access aligment issues in ImageBuffer3D::ExtractSagittalSlice + fix for wrong screen Y offset of mpr slices in DicomVolumeImageMPRSlicer.
