20040614:IDV Level II data RHI display

Unfortunately that is the only way to change the scale in the graph. 
That is in our TODO list:
"  - RHI - Do we want to allow the user to change the scale of the XS  
display?"

The azimuth indicator allows you to change the both the azimuth and the 
length of the cross section.

I'm not sure what "dealiased" means, perhaps Don (who is out this week) 
would be able to have a more informed
conversation about this.
