30 : Left/Right margin and first line indent
31 :
32 : SvxLRSpaceItem offers two interfaces for views from the left margin and
33 : first line indent. The get methods return the member, with the layout also
34 : as expected: the left edge shifts to the negative first line indent to the
35 : left. The SetTxt/Gettxt methods assume that the left side represents the
36 : 0 coordinate for the first line indent:
