/* [Description]
Left/Right margin and first line indent
SvxLRSpaceItem offers two interfaces for views from the left margin and
first line indent. The get methods return the member, with the layout also
as expected: the left edge shifts to the negative first line indent to the
left. The SetTxt/Gettxt methods assume that the left side represents the
0 coordinate for the first line indent:
UI UI LAYOUT UI/TEXT UI/TEXT (Where?)
SetTextLeft SetTxtFirst GetLeft GetTextLeft GetTxtFirst (What?)
500 -500 0 500 -500 (How much?)
500 0 500 500 0
500 +500 500 500 +500
700 -500 200 700 -500
