[HOT] How to fully cover a grid square.

Hi Pete,

I have really wanted something like has been discussed in this thread 
for a while now.

Your opaque indicator of reviewed areas reminds me of an idea we had for 
a JOSM plugin to help with these scanning type mapping tasks:

One of those overhead "spotlights" that follows you around and "exposes" 
land by illuminating the areas you have "walked" through like in an 
online mmorpg game. So you could easily see where you have already been 
because that was lit up and the darker areas around you needed more 
"exploring" to get revealed.

Just a nutty idea AndrewB, Zverik and I kicked around a few months 
(year?) ago to make mapping a little more fun, interactive, exploratory 
and thorough.
