Mark several points at once in image viewer since its is faster to render than looping over markPoint method for all the points.
Unlike the markPoint method the drawn shape is a square (cheaper at rendering) in background color with its center in foreground color.

This is faster then looping on markPoint since all the markers are placed in the
same actor and rendered only once.
