Get the RGB values for the pixel under the mouse.

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 ""

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.
