[Laszlo-user] Your vote needed: Text formattingand datapaths

[Peter Brand]

Hi all 

Before beeing able to vote I should understand: How do formatting according
to #1 (using attribute 'layout') and formatting acordung to #2 (using
method 'format' and string-argument '%s %s') compare? While #1 obviously is
simple layout along y-axis, I cannot see in what kind of 'formatting' is
specified by the string '%s %s'. What, precisely, is that string about to
do, what's its meaning? Apologies, if that' a silly question.

Peter

#2 is good. Keeps things (moderately) straightforward and reduces the
amount of complexity for users and for implementors.
