Before I can write a full usage documentation, here are a few things
to remember in using Mirage:

1. the upper-left column of buttons are for opening new pages:
   to make a new page, delete the current page, or renumber existing pages

2. the lower-left column is for configuring a page of plots.
   just click and DRAG the wanted plot over a blank page.   you can tile
   the pane using the tiling buttons (all dividers are movable).
   any blank tile can be covered with any of the plots.  
   the big cross is for deleting a plot.

3. the right column of buttons are for mouse operations.
   the top set is for repositioning or rescaling a plot (effective only on 
   some types of plots such as the scatter plot).
   the red set is for drawing a region in a plot.  the rectangle works for
   every thing (except tables).  the irregular ones work for scatter plots
   only.

4. there are two buttons for toggling between "monochrome" or color mode.
   press either once and click the mouse at the plot you want to change
   to monochrome or color.

5. there is an "union/intersection" toggle for successive selections.

6. the other buttons are for operations on the selected points:
   you can color them or bring them up as isolated plots.
   finally there is the "broadcast" button that broadcasts a selection
   to all VISIBLE plots  (hidden pages need a re-broadcast when they become
   visible).   the last button deletes any existing selection.
