20050420: IDV - point data plot resized by reset view

[Jeff McWhirter <jeffmc@xxxxxxxxxxxxxxxx>]

> Inquiry: Making special point data symbols in the geon idv java package, using extensions to the class MetSymbol, with method makeShapes, the shapes' size is controlled
> by the display control window's "Scale: entry box.
>
> If you use a large value in Scale: to see the symbols in more detail, then click the reset the view button (Ctrl-R), the symbols are rescaled to size 1.0. Changing point of view (not zooming) should not change size of data symbols.
>
>  
Scaling and auto-scaling of symbols is an ongoing problem. We will try 
to address it in the next release.
