Hi,

I measure integrated intensity along a freehand line of interest.
It would be useful also to measure this in the region defined by a
thickened line, but setting line width > 1 produces IntDen = 0. It
appears to work for single straight lines, but not freehand. If it
is relatively easy to implement, I would very much appreciate this
to be considered as a future feature.

I also noticed some strange behaviour in the Line Width dialog
(ImageJ 1.43n under Windows). If width is changed, then the dialog
is closed, then reopened, clicking on the scrollbar to decrease the
width doesn't change the value displayed. Also the scrollbar does
not reflect the displayed value - e.g. when it is 150, the scrollbar
is positioned to the left rather than the middle - until the value
is changed by editing.
