Also, if you just want to "see" ROIs in different colours, you can always
create and label a new empty image where the ROIs are drawn in different
colours (using the macro setColor() and draw functions.
This is quite useful because:
1. the labelling remains in the new image but ROIs (at the moment) do not.
2. one can retrieve back the label by looking at the colour of the (XStart,
YStart) pixel (you only need a results table open, or those coordinates
stored in an array).
