0004 Transition area.
0005 The idea behind this parametrization is that:
0006 one glass module with its wrap is always
0007 a size of 4 crystal modules with its wraps.
0008 Then the transition area (where glass meets crystals) has no gaps

0020 This implies that:
0021 GlassModule_wrap = 2*CrystalModule_wrap
0022 GlassModule_sx = 2*CrystalModule_sx
0023 GlassModule_sy = 2*CrystalModule_sy
