-PPI display will be done later. 
+Details for PPI display:
+
+Located on right hand of the screen. Put 1/2 inch margins on the right and top and bottom.
+
+The PPI display will need shaders for the following:
+
+1. Active radar target echos (blue white phosphor)
+
+2. Graticule (warm incandescent color, it was a plastic overlay lit with lamps. Does
+   not get included with persistant phosphor. Can change if the operator changes the
+   range. Have ticks for bearing; each degree. Every 10 degrees have a small text label, put these
+   outside the ring. No range rings for now. Have to figure out how that is done with vintage
+   radars. Perhaps you can suggest. Does operator have to change the plastic graticule when they
+   change the range?
+
+3. facility to change clutter, rain and waves. Immediate is blue white same as targets
+
+4. facility to include shore lines. This will change with range settings. If possible, can
+   we include docks and tall buildings? Immediate is blue white same as targets.
+
+5. Persistance (green yellow) for targets, clutter, and shore lines.
 
 Right  now, I just want to make sure that the structure is okay and that the CMakeFile.txt
 looks okay. I am  not ready to ask you to create any code
