Get the RGB values for the pixel under the mouse.

[James Hurley]

This may go under the heading of "what I did with RR today."  
Marginally useful.

We just received the California Department of Forestry map defining  
the level of fire hazard:  Red for Very High, Orange for High, Yellow  
for Moderate.

I wanted to get the fraction of the Very High area in our county.

To be sure of my code I started with a script to get the RGB values  
under the mouse, using a MouseMove function.

To see this

go url "http://home.infostations.net/jhurley/RGBunderTheMouse.rev"

Unfortunately the map does not show pure colors so getting the ranges  
for each hazard zone is messy. But this utility is useful in  
exploring the range of colors.
