// I wrote this nifty little java program over a weekend because I needed
// a way to send pictures over regular email.  At the time I was working
// for Fujitsu Research Labs in Kawasaki Japan programming Java systems.
// Now I'm out at Starwave in Seattle WA.... Whatever you do, don't take
// this code to be representative of 'me at my best' because it is quick
// and dirty code and nothing more.

    //  (Computer industry humor)
    /// TO DO maybe...
    // (5) Add undo class that remembers a list of locations and previous colors and
    // a graphic object before an operation so I can undo anyoperation and do it quickly.
    // (6) Refine the color palette to be more like the usual kind...
    // (7) Add a rectangle tool, selection tool for moving and deleting, eraser tool and
    // a dropper tool (for selecting color)  --> hey YOU, yes YOU could do that!!! :-)
    // (99) Add "tip of the day" feature and somehow tack on 24 extra megs and a Wizard or two;
    // eventually write a book called "the road back"
