Zoom: enter a higher value to zoom out. A value of 1 means 100%, 2 means 50% etc. A fraction of 1 can be entered in order to zoom in (e.g. 0.5 for a 200% zoom), but the display will appear stretched.
Horizontal range: enter the min and max coords to display on the horizontal scale. Note that this will be limited to the horizontal sequence range that Dotter was started up with.
Vertical range: enter the min and max coords to display on the vertical scale. Note that this will be limited to the vertical sequence range that Dotter was started up with.
Sliding window size: affects cut-off limit for how dots are drawn
