WARNING "In-depth" selection with the Mouse Right-Click will select all the parts comprised in the selection rectangle, including occluded parts (meaning entirely hidden by other parts). Contrary to selection with the Mouse Left-Click that will not select occluded parts.
NOTE All parts crossed by the selection rectangle will be selected: they do not need to be entirely in the rectangle to be selected (one pixel is enough).
